Requested by americanarse: When taking down Thanos, Peter's the one who snaps his fingers, not Tony

My eyes fluttered open, coughs leaving my lips as my lungs breathed in the dust. I coughed harshly, my eyes squeezing shut. They opened again before widening.

"Fuck." I choked as I looked around to see that I was lying in the rubble of the now destroyed Avengers' Compound. You know, the one that Thanos had just blown up to steal the infinity stones from us. Again. I looked down and choked as my leg was stuck under a massive bit of concrete and water poured in all around me. I pointed my hands at my leg, my red energy igniting in my palms. It spread slowly to the rock, making me grit my teeth and grunt quietly at the power that I was using as I tried to lift the rubble and therefore free myself. I cried out, my magic failing to lift the rubble. I was too weak.

"Help." I croaked into my comms. But all I could hear was static.

"Help! Anyone, please! I'm trapped! I can't get out, help!" I screamed.

"We read you, Y/N! Someone's coming for you, hang tight!" Tony replied. I gulped and looked at the steady waterfall that was next to me, the flowing water rising around me.

"I can't hold on. There's water everywhere and it's rising. I've got five minutes, if that, before I'm underwater." I choked and shook my head.

"We'll get to you, it's okay!" Natasha responded. I bit my lip, tears starting to leave my eyes as I watched the water rising around me. This couldn't be how I died, especially not before I found out if the plan had worked and if Peter was back. Though in the current state of things, it looked like I'd never know.

"Guys, the water is rising, and I understand if none of you can get to me. But just tell Peter that I love him. Because he'll be back. I know that he'll be back." I choked as tears started to freely leave my eyes.

"Y/N, hold on, we'll make it to you, just hold on. We can't lose you too, kid." Tony replied, making me close my eyes and bite my lip as I heard a slight choke in his voice.

"I'm sorry. I'm so sorry." I choked as the water started to lap around my body.

"Y/N, hold on, for the love of god, please!" I closed my eyes and took a deep breath before the water rose over my face.

Peter's P.O.V

Peter's eyes shot open, a gasp leaving his lips as he shot up into a sitting position.

"Hey, you're okay, kid." Peter looked up at Doctor Strange as the man crouched beside him and placed his hand on the boy's shoulder. Peter gulped and choked, his eyes moving down as he felt his chest with his hands.

"What's the last thing that you remember?" Doctor Strange asked.

"I-I remember...my body felt weird, it was tingling, but not, like, my Spidey senses...and then, fuck, I must have passed out." he gulped. Doctor Strange sighed and looked at him.

"You didn't pass out, Peter. Thanos succeeded, he snapped half of us out of all existence. It's been five years." he admitted. Peter's eyes widened.

"Y/N. I left her for five years. Is she alive?" Peter choked.

"We're about to find out. Because we're joining the fight." Doctor Strange nodded as he raised his hands and started to create what looked like a golden circle.

"Woah." Peter mumbled as he stood up. He went to the circle, his eyes widening as he saw thousands of Wankandan soldiers coming out of other portals.

"Go on, kid. Join the fight. I know that you want to." Doctor Strange smiled. Peter returned it and nodded, his mask forming over his head as he jumped through the portal and attached his web to one of the ships. He landed with his hand in between his legs, his other arm up in the air as he stood up and his mask went back into his suit.

"Guys, the water is rising, and I understand if none of you can get to me. But just tell Peter that I love him. Because he'll be back. I know that he'll be back." Peter's eyes widened as he heard Y/N choke over the comms.

"Y/N, hold on, we'll make it to you, just hold on. We can't lose you too, kid." Tony replied.

"No. I'm not losing you now." Peter mumbled to himself before shooting a web at Scott's still huge form and flinging himself into the air.

"Karen, locate Y/N." Peter demanded.

"She's underneath the rubble of the compound. And the water is rising quickly." she informed. Peter nodded to himself as he used his webs to rush to where she'd been located by Karen.

"I'm sorry. I'm so sorry." Y/N choked over comms, making tears prick Peter's eyes as he rushed to her. He just hoped that he wouldn't be too late.

"Y/N, hold on, for the love of god, please!" Clint exclaimed.

"Guys, it's okay, I'm getting to her!" Peter yelled as he started to drop down into the ruins of the building. His eyes widened as he saw her. Under the water.

"Come on, Y/N, don't give up on me now." he mumbled as he dropped down to where she was.

Y/N's P.O.V

My eyes shot open and I gasped as someone pulled me out of the water. I coughed and spluttered, desperately breathing air into my lungs.

"Woah, you're okay, babe, you're safe." my eyes widened as I heard his voice. No, it can't have worked, surely, I thought as I slowly looked up. Peter smiled and bit his lip at me, making me choke.

"Hey. I'm back." he chuckled. I choked again, tears immediately starting to leave my eyes as I launched myself at him.

"Woah!" he exclaimed, a laugh leaving his lips as I tightly hugged him.

"I thought that I'd lost you. I've had five years without you, Pete." I cried into his shoulder.

"It's okay, babe. Because I'm back now, and I'm here to stay." he reassured. I pulled away but only enough to see his face as I leant in and joined our lips. He returned the kiss and smiled into it as he cupped my cheek.

"I hate to break up your reunion, but we really need your help to make sure that Thanos doesn't snap us all out of existence again." Tony spoke into our comms, making us break the kiss.

"Right, sorry." Peter chuckled. I smiled and bit my lip as Peter effortlessly lifted the rubble off of my leg, freeing me. We stood up and I used my powers to get out of the ditch, Peter launching himself into the air with his webs.

I fired all of my energy at Thanos, the villain moaning and groaning as we all surrounded him and tried to take him down. Tony, Wanda and I were firing all of our energy at him, progressively making him weaker as Peter held his hand open with a web and Steve and Thor tried to get the gauntlet off of his hand.

"I don't know how much more of this I can take, guys." I spoke through gritted teeth.

"It's nearly off, keep pushing! We're so close!" Steve exclaimed. And that's when it all went wrong. Thanos yelled out and pulled on Peter's web, making my boyfriend scream as he was sent flying.

"Shit, stop him!" Tony yelled as Thanos threw Steve and Thor off of him. My eyes widened as he started to close his hand.

"NO"!" I screamed as I raised both of my hands and fired my energy at the gauntlet. My energy immediately detached it from his hand, making Thanos growl as the gauntlet crashed to the ground.

"This is our chance! Is anyone close to the stones?!" I yelled as I aimed my power back at Thanos in order to keep him pinned down.

"I am." My eyes widened. My heart started to thump in my chest as Peter landed by the gauntlet before standing up.

"Tony, give me a glove." he demanded as he outreached his arm.

"Peter, no." I shook my head. He looked at me.

"It's the only way, babe. We both know it." he choked and shook his head as we heard the soaring of the capsule. It broke apart and landed in the form of a robotic glove clicking around Peter's hand. I shook my head, tears starting to leave my eyes as I knew exactly what he was planning. Peter leant down, the stones floating towards the glove that he now had on. His head flew back, a scream leaving his lips as the power of all six infinity stones started to fill him. He collapsed to his knees, his breathing laboured and heavy. He looked at me, making me choke and shake my head. He couldn't do this, he couldn't. Both of us knew that he wouldn't survive if he did.

"Peter, please!" I cried. He gave me a small smile, tears streaming down his cheeks as he just looked at me.

"I love you." he nodded.

"NO!" he snapped his fingers, light exploding from him. I immediately got thrown back, cries leaving my lips as I landed a few feet back. I coughed, dust filling my lungs as I looked up. My eyes widened as I looked around to see Thanos' army slowly but surely turning to dust. Meaning that it had worked. I looked towards Peter, my eyes widening further as he lay unconscious on the ground.

"Peter, no, please." I choked as I scrambled to my feet and started to rush to him. Tears started to leave my eyes as I reached his body, the right side of his face and neck badly burned and his suit utterly wrecked.

"Peter, please, stay with me!" I cried, his eyes fluttering open as I collapsed onto my knees next to him and gently raised his head to be on my lap. I choked and shook my head as I gently started to stroke his hair. I could tell by his laboured breathing and gasps that Peter was dying. My Peter was dying.

"Karen, vitals." I mumbled. I knew the answer, but I needed her to confirm it.

"All vital signs are failing." she informed. I squeezed my eyes shut and nodded, tears streaming down my face as I looked at Peter. The boy gave me a weak smile, making me bite my lip as I continued stroking his hair.

"Why did you do it? Why did you do that to yourself? I only just got you back." I shook my head.

"I had to save you, angel. I'd do anything to save you." he whispered. I choked and bit my lip, the tears flowing freely as Peter gently looked up at me. My heart hurt, my mind refusing to come to terms with the fact that the love of my life was dying in my arms. This really was it for him.

"Tell May that I love her. Tell her that I'm sorry, but that I was okay. You know, when it happened." he gulped. I nodded and returned his gulp, my heart breaking as I could tell that he was scared of dying. Not that I could blame him.

"I will, Peter. I'll tell her everything, I swear to god." I promised, my hands still gently combing through his hair and trying to make this as painless as possible for him. He looked at me, his beautiful chocolate eyes scanning over my face as his lips were set into a small smile. His hand shakily raised to cup my cheek, making me lean into his touch as I bit my lip.

"I love you so much, Y/N. I always have. You made my life worth living. I'm just sorry that I have to leave you. I'm so sorry. But just remember that I love you, so much." he whispered, tears rolling down the side of his face.

"It's okay, Pete. I love you too and it's okay. You can let go. I know that you're in pain, so you can let go." I nodded, forcing a small smile onto my lips in an attempt to reassure him that it was okay. In reality, my heart was being ripped apart. His eyes started to flutter, my breath hitching. He was close. This was really it.

"Thank you. For everything." he whispered before his eyes fluttered shut. My eyes widened, another choke leaving my lips as Peter's body went limp in my arms. My lip stayed in between my teeth, my body going numb as I knew. But I had to be sure.

"Karen, vitals." I whispered.

"There are no vitals. I'm sorry, Y/N. Peter is gone." she spoke gently. I gulped, my mouth hanging open as my entire body went numb. Tears rolled down my cheeks, though I barely felt them as I just continued to hold Peter's body.

"Y/N." I looked up, my vision blurry and my eyes puffy as the rest of the team stood around us. Tony looked at me, tears running down his face as he looked at Peter's body.

"I'm so sorry, Y/N." Tony choked and shook his head. I bit my lip and looked back down at Peter's face. His eyes were closed, and he looked so oddly peaceful. Half of his face was now burnt, but he still looked as gorgeous and handsome as the first day that I met him. But now, he was gone, and he was never coming back. And there was nothing that I could do this time to fix it. There was nothing. I felt numb, my ears starting to ring as I could hear and feel nothing. All that I felt was my hand still rested against Peter's curls. I didn't want to move. If I moved, I had to say goodbye to him, and I wasn't ready for that. I didn't think that I'd ever be. More tears streamed from my eyes, my mind slowly but surely starting to comprehend the fact that yes, Peter, the love of my life was gone for good. And all it took was a snap of his fingers.
