"So the fuck do you!" Mark snapped back before he could stop himself but he was immediately wincing at his tone, squeezing his eyes shut and putting his hands over his face. What he really wanted to say was the he didn't need sleep, he needed a drink. It was his fucking brain pulling bullshit on him again. Booze was the last thing he needed but the cravings felt like they were eating up his insides like acid. He was exhausted and his fuse was short. It wasn't far to aim any of that at Sam, who he knew was struggling with his own shit.

He lowered his hands and rubbed his sweaty palms on his thighs. "You're supposed to be starting chemo, Sammy. This is so fucked up. My twin with bloody cancer is sitting here telling me I need to try to get some rest. You shouldn't have even left hospital when I got that call about the accident. Are you putting it off? I can't let you use any of this to put off your treatment. You look really fucking crook, okay? I know that's bullshit coming from me right now because I don't look much better. But this isn't going to kill me. I know you're worrying yourself sick about me hitting the booze and I'm promising you, I'll go and try to get a kip. Only if you promise me you will too. Gen and Alexis, they're probably better equipped to be here at the moment anyway. Jus would probably freak out if he woke up and we're both sitting here looking like something out of the Night of the Living Dead. I just..." He stopped to take a deep breath. "Are you using me as an avoidance tactic like I'm using booze? You've been straight with me about everything? It's not worse than you're letting on?"
