Oh goodie..
After a long mission, you and the crew decided to go out and get something to drink. You also agreed that you weren't going to drink (also because you don't) because they needed someone to get them home. Plus, they didn't have any call or way to get home so you had no choice but to agree taking the crews drunk asses home.
You guys found a small but comfortable bar, with barely anyone there. It was decorated like some 90's emo band obsessed teens room. So you decided that they were going to drink here.*
Many tall glasses of beer, four rounds of shots, and lots of karaoke, everyone was wasted. Some passed out on the floor or laying on tables, some throwing up in the bathrooms.
But Ghost?
He was still drinking so you decided to try and stop him before he over drinks and passes out.
