1- Insist that it's him
2- Be petty
3- Help Salem
4- You were glad to see him
5- Play along
6- Sure, I'm down for anything
7- Down the hatch
8- Got any seconds?
9- Accept
Ending 3 (?)
1- Insist that it's him
2- Do it out of spite
3- Don't help
4- It's whatever
5- Just head back
6- ...?
7- Sure, I'm down for anything
8- Down the hatch
9- That was gross
