It had been three weeks since the groups arrival in Vegas. Three weeks of partying. Three weeks of relaxation. Three weeks of getting drunk. Three weeks of fun and freedom. And three weeks of hookups (both drunk and sober).

The group had never had so much fun in their whole lives. Every night was a new adventure to them. They had been to 5 different casinos and 6 different clubs since their first night. They were having a blast.

But for one unfortunately soul the past few days hasn't been as much fun as they thought it would be.

For the past few days, Mikasa has been waken up by a sudden need to empty her stomach of everything she had the night before. Eren was confused as to what was going on with her, yet the poor girl didn't know. Each time he had asked her, she would just brush it off and say that it was nothing.

This morning was no different. The two slept peacefully as Mikasa laid in Eren's arms, when something abruptly woke her up. She opened her eyes not knowing what had interrupted her sleep. She began to look around the room. She turned her head to see Eren still in bed and holding her close to him. She smiled at the image before her and snuggled back into his warmth.

Just as she laid her head back on the pillow, Mikasa felt a wave of naseau wash over her. Without a second thought, she threw the covers (along with Eren's arm) off of her taking off towards the bathroom. She lifted the toilet seat and felt the burning sensation of the bile coming up her throat from her stomach.

Eren woke up as he heard someone throwing up. He felt the light from the bathroom start to blind him as he sat up and look around the room for his best friend whom he could have sworn he'd fallen asleep with. He moved towards where he assumed she was.

Upon reaching the bathroom he looked over at her feeling not surprised, but concerned for her. He walked closer to her and crouched down next to her. As an attempt to let her know he was there for her, he grabbed her hair pulling it out of her face and began rubbing her back. "Mikasa, what is going on with you? You've been getting up in the middle of the night to throwing up for days now. Are you ok?" He questioned hopeful that she wasn't hurt or really sick.

"It's nothing Eren. It's probably from all the stupid alcohol I drank last night." She replied lifting her head from inside the toilet.

"That's the problem Mikasa, you didn't drink anything besides water last night." Eren said handing her some tissues to wipe her face.

"Eren, really it's nothing. It might just be a stomach bug or something." Mikasa said as she tried to reassure her friend that she was ok. She had wiped her face and flushed the toilet she'd just thrown up in. She walked towards the sink to brush her teeth so she wouldn't have the lingering taste of bile in her mouth.

Eren got up and moved to leave the bathroom. He leaned on the door frame, watching her as she washed up.

Mikasa could feel his gaze on her and tried to pretend that she didn't notice. She finished up and turned towards where he was now standing. She grabbed him by his shoulders, giving them a gentle squeeze as an attempt to reassure him one final time before saying.

"Really Eren, I am fine. Now can we just try and not worry about me right now. Let's just go back to bed, it's too early." She smiled and started to walk towards the bed and getting under the covers.

"Fine, but just so you know, this isn't over Mika." He said crawling into bed with her once again and taking her in his arms.
