Mark Sloan sat at the bar drinking his beer. He thought about how stupid he had been with Addison and everyone else. He was just tired of being him. For once in his life, Mark wished to be someone else.

Derek Shepherd soon sat down beside Mark. They hadn't been on speaking terms lately, but Derek was feeling the same way Mark was. Tired of being himself. Tired of Addison and Meredith. Just...tired.

"Hey, Derek," Mark said, his voice scratchy from being tired and probably drunk.

"Mark," retorted Derek. He downed his beer within the course of only two drinks. Derek then grabbed another drink and downed it.

"Woah. Slow down. You'll kill yourself," Mark said quietly.

"I don't want to kill myself. I just want to get drunk," Derek said.

"I hear you there, bud." Mark and Derek clinked their glasses together before downing them in seconds.

Hours later, Mark and Derek were too drunk to even consider the possiblity of driving.

So, Walter drove them back to Mark's apartment. They walked up the steps, swaying from side to side.

Mark unlocked the door and he and Derek swayed into his apartment, laughing over nothing in particular.

They eventually started talking about Addison.

"I'll never love her again," laughed Derek.

"I'll never stop loving her," laughed Mark.

After that, they just laughed.

Eventually, they stopped laughing. Mark still smiled, though. "I don't want to talk about her anymore."

"Me neither," agreed Derek.

Mark suddenly kissed Derek, and, at the end of the night, they ended up naked in Mark's bed.

Derek was the first one to wake up in the morning. His head was pounding, and his mouth was dry and tasted terrible. He looked to the side, not expecting to see a naked Mark lying next to him.

Derek then remembered last night. The alcohol, the laughing, the talking, the kissing, and finally, the naked part.

Mark finally woke up. He ran a loving finger across Derek's uncovered hip, smiling. "Last night was--"

"Last night didn't happen," Derek said slowly, pronouncing each part carefully.

Mark sat up. "What? Why not?"

"Because it wasn't supposed to happen. You're my best friend, not my lover," Derek explained.

"Leave then," said Mark, looking away from Derek.

Derek wanted to leave, but he couldn't bring himself to do it. He looked at Mark's back. The intricate lines were perfect. Derek then looked at Mark's naked butt. It was cuter than he had ever remembered it before, not that they had done this before.

"Look, we were drunk," Derek said plainly.

Mark turned to look at Derek, and Derek noticed the perfectly toned muscles of his chest and torso. Mark sighed. "But we don't have to be drunk."

And Mark kissed Derek.
