They’re clearly saving Reva’s backstory for a later confrontation with Kenobi.
The kid playing Leia did a great job in this episode.
The change of heart about helping Ben was a little too quick, but Wade’s death was not about the audience caring about Wade as a character (we don’t, and that’s fine), it was about his death’s effect on the characters, some of whom are now seeing just how much their personal involvement in the Path can cost, others feeling unworthy of having had someone give up their life to save them.
Vader’s confrontation with Reva, at least in the closeups, was definitely Hayden in the suit. Something about the body language was very PT-Ani.
Wade certainly will become a meme, that’s for sure.
