Later that night, McKenzie's phone lit up with a text from Clint: anything interesting happen since the hospital thing?

McKenzie smiled, looking over at the Doctor, who had fallen asleep hours ago. You could say that, she replied. My wing is completely healed!!!

Another text came through within seconds. That's great! You can fly and everything now?

Yep!

Clint replied after a few minutes. Why don't you drop by tomorrow, then you can show me. We can get pizza, and I can finally meet Martha.

McKenzie grinned. Sure. Send us time date and place and we'll see you then :p Once the message with the details came back, she said goodnight to Clint and went to sleep, ready for a day of fun with her best friend.

"Kez?"

McKenzie rolled over, ignoring the Doctor gently shaking her shoulder.

"Kez." He sighed. "McKenzie. Come on, I know you're awake." She cracked open one eye and peered at him. "Morning, gorgeous," he greeted, kissing her forehead.

"What do you want?" McKenzie groaned, rolling over to look at him properly.

"Clint's texted you." He handed her her phone.

"Ooh!" she exclaimed, wide awake now. "What time is it?"

"We're in a time machine," the Doctor reminded her, raising an eyebrow. "Why, what's he want?"

McKenzie grinned, getting out of bed and grabbing a towel. "Last night I was telling him about my wing being healed, and he invited us round to the flat." She chucked her phone at him, the text open. "Time, date, location there."

The Doctor read it as she went into the bathroom, closing the door behind her. "He's in London?"

"What?"

"Clint's in London?" he asked, louder this time.

"Oh, yeah. Apparently Nick gave him someone to keep an eye on, see if they do anything suspicious, y'know?" McKenzie replied. "I think he's a bit bored. He's usually doing more adventurous stuff, but I think Nick's making him take it easy for a while after the whole mind control thing."

"Right." The Doctor paused for a while as he got dressed. "You having a shower?"

"Mm-hmm."

"Okay. I'll go put the time and that in, see if I can find Martha," the Doctor stated.

"All right. Give it twenty minutes, and I'll be done," she called back, before turning on the shower and grabbing the shampoo.

True to her word, McKenzie appeared in the console room twenty minutes later, her hair combed straight and damp. "Morning," she called as she entered, kissing the Doctor's cheek as she reached the console.

"Morning," Martha replied, gripping onto the console as the Doctor started the dematerialisation sequence. "I hear we're meeting the infamous Hawkeye."

McKenzie shrugged. "Well, you are. The Doctor and I already know him. In fact," she said as they landed. "He saved my life."

The Doctor snorted as they exited the TARDIS into a nicely furnished flat. "I think you returned the favour well enough."

She rolled her eyes. "He did set my wing back too," she reminded him, before looking around. "Clint?"

There was no reply. The Doctor raised his eyebrows, looking at McKenzie's phone before handing it back to her. "We got the right time. And place."

Martha shrugged. "Maybe he's running late or something."

McKenzie frowned. "Clint's not the kind of guy who gets up much before nine, and it's twelve now. If he had to go out, he would have done it last night." She called his name again as they entered the lounge, then sighed in relief as she saw him sitting on the couch with a packet of pop tarts and an article up on his laptop. "What, are you deaf?" she asked playfully, ruffling his hair. He jumped, grabbing his laptop so it wouldn't fall, then looked up, relaxing when he saw the trio watching him weirdly.

"Oh, hey guys," he greeted, speaking a little louder than needed as he closed his laptop and got up. He hugged McKenzie, shook the Doctor's hand and then said, "Martha, right?" The girl nodded, and he grinned. "Hi. Uh, make yourselves at home, I guess, I just need to grab something." He then walked into another room, presumably his bedroom.

The Doctor rolled his eyes at Martha's surprised expression. "What, did you think he'd have his bow at you?" They sat down on the couch with McKenzie.

"I don't know," the human said. "I guess I was expecting him to be more... Stern. Like, he's an agent, and he wasn't exactly too expressive during the war."

"See, that's the thing about wars with advanced species," Clint said as he walked back in, fiddling with what looked like a flesh coloured ear bud. "It's so freaking surreal, you just gotta laugh and fuck their shit up, if you don't mind the language."

McKenzie was watching him. "I didn't realise you were deaf," she mentioned as he took a seat.

He shrugged. "Last time we saw each other, we were facing the press aftermath of a intergalactic war. It wasn't time for show and tell."

The Doctor smiled. "I did wonder how you could see so well. I thought maybe you were just special."

Clint snorted. "That's what Natasha says, but I don't think she means it so nicely."

"You've worked with the Black Widow?" Martha asked.

"Yeah. She's my best friend." At McKenzie's raised eyebrows, he rolled his eyes. "Alongside Featherhead over there."

"Featherhead?" she repeated indignantly.

"Healed up nice," he remarked.

"Yeah, it took ages," she complained.

The Doctor rolled his eyes. "It was three months, Kez."

"Exactly! And two of those months were spent lying around doing absolutely nothing because somebody said I should over exert myself!"

Martha watched Clint as he laughed at them. "They did this with you too, huh?"

"Well." He made a face. "It was weirder then. The others had known them before we went to war, because I was... Otherwise occupied... So I wasn't exactly used to it. But it was cute, all the same." He pointed to McKenzie. "This kid cracked so many puns whilst we were at this shawarma joint, Bruce nearly Hulked-out all over again. It was priceless. I have never seen Natasha scowl so hard."

"Thor seemed quite impressed actually," the Doctor added, smiling nostalgically.

"I think it was the first time I ever saw Steve and Tony agree on something," McKenzie laughed. "They hated it!"

"But where did you put away all that food?!" Clint asked, pointing at her. "You must have eaten your weight in shawarma!"

McKenzie blushed. "Hey! I hadn't had exertion on a scale of that battle since year ten hockey. I think I earned my fair share. Besides, did you see Steve? He was falling asleep!"

The Doctor laughed. "He'd barely had anything. Honestly, that's the only time I've seen him act his age."

Martha was looking between them in something between shock and awe. "You guys know each other pretty well then."

Clint shrugged. "Three hours after we met," he said, pointing between himself and McKenzie. "She throws us out of a window on the eightieth floor of this office block. And the only injury sustained was a dislocated wing."

"Yeah, and minutes later, you're playing nurse to it," McKenzie smiled nostalgically.

"I never did thank you for that," the Doctor mused.

"Nah, that's okay. She's a funny kid. Even Nat liked her, and with our job, she doesn't exactly trust easy," Clint waved it off.

"Would you believe it, we only really knew each other for a few days?" McKenzie laughed.

Martha raised an eyebrow. "Well, you didn't know he was deaf."

The Doctor shook his head. "That doesn't count. We were all distracted. She was injured. And, come on, we'd just fought a war. We were hardly checking if our favourite archer guy was deaf."

Clint grinned. "I'm your favourite archer guy?"

"Sorry, Barton, but you're also our only archer guy," McKenzie pointed out.

"That, Di Angelo, is besides the point," Clint stated, getting up. "So, your favourite archer guy is getting pizza. Who wants in?" He grinned as they all volunteered.

***

When it was ready, Clint and McKenzie sped down to the pizza place, stopping in a nearby alley before walking out. A young couple saw them and started chattering excitedly. As they came over, Clint groaned and swiftly removed his hearing aids.

"Are you Hawkeye and the Angel?" one of the boys asked, already getting out a phone for a selfie.

Clint started making confused gestures and expressions, while McKenzie just started rattling off in a foreign tongue. Pretty swiftly, the couple gave up and went away, leaving Clint and McKenzie to go into the pizza place laughing their heads off.

"What language was that?" Clint inquired as he replaced his hearing aids.

McKenzie shrugged. "I think it was Croatian." She grinned. "We just did the thing."

Clint looked confused, for real this time. "What thing?"

"'If we get caught, you're deaf and I don't speak English'. I've always wanted to do that."

Clint nodded. "I've done it with Nat a few times. She always found it fun, but I couldn't hear the reactions, so that took away from the effect, I think." The redhead laughed.

"Thanks," McKenzie smiled as they took the pizzas and left. They went straight to the alleyway and joined hands. "Ready?" she asked. He just smiled.

"I still can't believe you eat Hawaiian," Martha said, shaking her head.

"What's wrong with ham and pineapple?" the Doctor asked indignantly.

"It's just not right," Clint told him. "Why Hawaiian when you could have barbecue chicken?"

"Or four seasons," McKenzie added, rolling her eyes fondly.

"Even mozzarella is better than Hawaiian, and there's hardly anything to it," Martha continued.

"I like Hawaiian," the Doctor said reproachfully. "It's like ham, egg and chips, without the egg and chips." The others looked at him weirdly. "Yeah, that was bad, I know."

"But doesn't the pineapple soak through the crust?" Clint questioned.

McKenzie pointed at him, nodding. "Nothing worse than a soggy bottom."

"Ah, but if you get deep crust it's fine," the Time Lord reminded them.

"Whatever, man, it's still disgusting," Clint shook his head. "Barbecue chicken is always gonna be better."

The Doctor snorted. "Sure."

"C'mon ladies, let's settle this nicely, eh?" McKenzie suggested. "Repeat after me: Four seasons is the best." She yelped as Clint threw a cushion at her with pinpoint accuracy, then pouted when the Doctor nicked some of her drink. "Guys!"

Later on, Martha was showing McKenzie around this area of London—it was quite near to her hospital—while the Doctor and Clint stayed up at the flat. They were stood at the window, watching as the girls skipped across the plaza.

"She seems so young and innocent," the Doctor sighed. "I still can't believe she survived the war."

"How old is she?" Clint asked, curious. He knew she was the youngest out of the Avengers, but he hadn't wanted to ask her directly. From past experience, he knew that was a bad idea. "I mean I guessed something like twenty seven, twenty eight, but..."

The Doctor winced. "She's twenty next month."

Clint whistled lowly. "Shit."

"She was so brave. I didn't expect... I'm so proud of her. She's come so far..." The Time Lord shook his head.

Clint frowned. "She told me there was a guy. Is that what you mean?"

The Doctor nodded. "It's not my story to tell, but... It helps if someone else knows, in case she needs me and I can't be there." Clint moved to the couch, and he followed. "Nearly four years ago, she was engaged to this guy. Long story short, she wanted to break it off, he said no, and he ended up raping her." Clint's eyes widened. "She used to barely let me touch her, even holding her hand while we ran. And now, look at her. She's so comfortable around you lot, always has been. The only one she's remotely scared of is Natasha, and that's cause she's freakishly talented at fighting."

Clint nodded. "Nat used to be the same. I don't know what happened, but even now she's wary, y'know? Maybe we should pair them up sometime."

"They'd end up inseparable," the Doctor laughed. "Steve would be terrified."

"I would too!" Clint agreed. "But they'd be good for each other, I think."

"Yeah," the Doctor nodded.

***

Much later in the day, the sun had set over the London skyline, and McKenzie was falling asleep against the Doctor's shoulder.

"Martha, you up for another trip tomorrow?" he asked.

Martha rolled her eyes. "I'm always up for another trip tomorrow. Where to?"

The Doctor frowned. "I don't know. Maybe we'll set it to random. D'you want to come, Clint?"

"No thanks. I'm working, and I know she's a time machine and all that, but Fury would know." Clint shook his head. "But I was thinking. From what I've heard, you just did New York in the future, albeit on a different planet. You've done present day New York, in the battle. How about past New York?"

McKenzie raised her eyebrows. "Actually, that's a good idea."

Clint frowned. "Well, what did you expect?"

"I kind of thought you were gonna start off about this 'perfect sandwich' again," the redhead confessed. Martha and the Doctor laughed, while Clint pouted.

"It was just so good..." he trailed mournfully, before laughing too.

"Old New York sounds alright," the Doctor mused. "Martha?"

"Sounds good to me," she agreed.

"Old New York it is, then," McKenzie smiled. "Now, does anybody mind if I crash, cause I'm gonna do it anyway."

Clint rolled his eyes. "By all means, Angel."

She yawned. "Night, guys." And then she was out.

Martha sighed. "Wish I could do that." The Doctor and Clint laughed.
