I'm not dissapproving of the storytelling choice, mind, because as opposed, say, some season 2 episodes, I'm sure this time around the writers do want me to see this as a rotten action on Jack's part

I don't remember too much of S2, but yes, Jack's inaction did seem to me to be portrayed as reflecting badly on him.

Richard's warning that this will make Ben one of them forever, had strong fairy tale elements, which works with the overall mythology

Good point about the fairy tale, though see my LJ entry for my reasons for potentially disliking this.

one of the Hostiles says Richard should ask "Charles" first and Richard says he doesn't answer to him.

They also mentioned Ellie! *Before* Charlies, iirc.
