I wonder why Bobby decides at that moment to stand up to Tony. Tony had verbally abused Janice right in front of him several times before that. I know Bobby was drunk this time, but you have to believe they'd been out drinking together before. Maybe the mountains just made him more rugged. After all, it was Pine Barrens where Tony began to respect Bobby as a legit soldier instead of just Junior's caretaker, considering Christopher might have died out there if not for Bobby's wilderness skills.
