Few things:
The junkyard folks must have played Mortal Kombat before the apocalypse. You could substitute Winslow for Goro or Reptile and it's a similar bout of test your might.
Daryl protecting Carol from the truth...I imagine it's because she's been through enough as it is and he'll tell her later. That said.
I get the feeling, even though they have thick plot armor, that either Daryl or Rosita could meet an end later. Rosita partially because she's so dead set on going out on her own, and Daryl just because he could end up being spotted by the Saviors since they're already looking for him.
Not sure what to make of the junkyard folks, but hopefully they become reliable allies for Rick and company. Or at least Jadis keeps her word, anyway.
And yeah, I think someone's going to have to die to push Ezekiel into joining the fight because right now his followers are getting their butts handed to them and he's telling them to stand down. And Morgan losing his stick? That's gonna be a turning point for him.
