Marc and Nicolas, when Marc still earned a (sort of) honest living with the army, and Nicolas still went to his extremely expensive college. Marc didn't get much time off, but when he did he'd visit Nic and unavoidably they'd spend the time either drunk or arguing, because they're the type of brothers who drive each other crazy. On a side note, I drew this without thinking of what Nic had given Marc to read, but the more I think about it, the more convinced I am it's a dirty limerick.
