@walidras: Likely after finishing the main game, and the other expansion (Hearts of Stone). The recommended levels seem to be slightly above those of the end-game sequence.
@Kathos: Given what Negan said ("Takin' it like a man!") when he was beating him/her, was I'm thinking it was Daryl too. But the whole "if Daryl dies we riot" thing has been going on forever, so they have legitimate reason to be afraid of killing him off.
I honestly couldn't say with any confidence who it was.
