after a successful mission, the Task Force decide to have a party before their day off, knowing they'd be hung over the next day.
after a few hours, you decided to speak with Soap, tell him he did a good job that day, just as you'd done with everyone else.
it took you a long time to find him, the place was so crowded with everyone that you didn't see him sitting with Ghost, straddling his lap, and looking VERY drunk.
you'd already spoken to Ghost, he was sitting in that same chair in the corner when you had. but now, Soap was also sitting there, hugging Ghost loosely, just enough to not fall off, while Ghost just sat there, looking blank behind his mask.
when you looked closer, you could see Ghost was steadying Soap so he didn't fall. his eyes were wrinkled slightly, showing a small smile from behind his mask as Soap was pressed flush against him, leaning back and letting it happen.
Soap was also wearing Ghost's jacket.
