I think you’re right about ROTJ, and that kind of touches on what Dr. Dre also said.
I think in general Obi-Wan kind of comes off as sort of a jerk to Luke when they have their conversation. First, Obi-Wan pulls the whole “certain point of view” card, instead of just apologizing for lying to Luke.
It’s such a weird scene ha, probably my least favourite in the OT. It’s an obvious and understandable lie on Ben’s part, just cop to it old man. Watching later entries in the series try to justifiy and further explain it is always so awkward to me too.
