Immersed: Alex Karev✓

One-Shot

A one shot of what would've happened if Cassandra was never sick. Season 7 timeline

Cassandra stood next to Derek at the counter of the bar, he was getting ready to leave and return to his wife, "go Der. I'll be fine."

"Not only is it your twenty-first birthday but you happened to be born on Halloween. The crazies are out. Be safe and see you tomorrow at the hospital for lunch."

"Of course. Goodnight. Tell Mer I said hello." she kissed Derek's cheek before returning to her friends. They were at this karaoke bar in town and they were flipping through a binder of songs they were possibly going to do, "what are you gonna sing, Mason?" she asked her brother, who had his boyfriend next to him.

"I'm not the singer. You're. I already picked a song for you." her brother gave her a grin.

"What song?"

"That one you like from Rocky Horror so much." the girl grinned and took off her jacket. Revealing a black outfit that clung perfectly to her body. The recent college graduate grabbed her drink from the table and down it.

"When is it my turn?" she asked.

"Next up we have Cassandra Manning."

"I guess now." Mason said with a smile.

Cassandra got lost in the song. So lost in the song that she was now grinding with some guy because karaoke hour had come to a close and a DJ was now playing in the bar. She didn't know anything about the guy except that he kept buying her birthday shots and that he was a great kisser. She didn't remember much about anything until the next morning and she rolled over in an unfamiliar bed and was surprised when there was a naked body next to her own. She lifted her head and admitted the stranger was cute as hell.

"You don't remember my name do you?" he asked looking over at her.

"To be honest. I don't remember much of anything after singing karaoke."

"Well after your song. Which was sexy as hell by the way. Thank you for using me as a model. We kept taking shots together, we took a cab to my house and here we are." she looked over at the clock.

"It's eleven. Shit. Shit. I'm gonna be late." she tore the blankets off her body and got dressed in the clothes she had on last night, "Derek is gonna kill me."

"Who is Derek?"

"He's like my dad, but not my dad." she looked over at male, "umm thanks for the birthday sex. I imagine it was amazing because you look experienced?"

"Maybe we can do it again sometime."

"Doubtful because I kind of have a boyfriend back in England. Which I go back tomorrow. SHIT. I have a boyfriend. I have royally fucked up. He's gonna break up with me."

"Well apparently he didn't mean that much to you if you slept with me."

"He didn't. But still. We have been on the rocks for months. Verge of breaking up before I came here to celebrate my birthday. Oh well." she shrugged and pulled out her phone and dialed a number.

"What the hell are you doing?"

"Calling Robert."

"Your boyfriends name is Robert? Is he sixty?"

"Fuck off. What's your name even?"

"It's Alex." she smiled over at him.

"Cassandra- Hello? Yes who is this? Oh. Well Sophie this is Cassandra, Robert's girlfriend of three years. Tell him when he's woken up that I slept with someone else too and that we are finished. Bye now Sophie." she hung up the phone and shrugged, "guess we both cheated. Oh well."

"Three years and you say oh well?"

"You don't know Robert."

"No I don't. But I also don't know you."

"I really gotta go."

"I'll show you out." Alex put on a pair of shorts and they walked out of the bedroom and into the foyer, "well that was fun."

"It was. Let's do it again?"

"Please." Cassandra looked over to her left feeling multiple sets of eyes on her, "shit. Holy shit. Meredith."

"Cass?" Derek rounded the corner and she stood behind Alex begging to be shielded from the man she thought of as her father, "what are you doing here? I thought we were meeting at the hospital."

"This is the Derek you know?" Alex asked.

"You live with the Derek I know? You're Alex Karev, you work at the hospital." she nodded her head.

"She just came downstairs with Derek." Meredith said, giving away the two. Derek's eyes went wide.

"Karev? You slept with my twenty-one year old God daughter?"

"In my defense I didn't know that she was your God daughter when we slept together." Derek looked like he was going to kill Alex and now Alex was behind Cassandra.

"Let's go, Cassandra. We can discuss this all during lunch." Derek said grabbing onto Cassandra's hand.

"Call me." Alex called after her, waving her off.
