My immediate thoughts are: Vash is 100% going to be "sacrificed" as he's missed quota a lot. Tim never has missed one, but he could also go as a "good example" Edit:Tim's plotting postEdit again:Vash plotting post
And the reverse could work for Tim. Maybe get him in trouble and he's saved by someone he would consider to be a monster. Or have him show some growth by him saving someone unexpected because sitting by and watching someone die is rough
