Fair enough, but given that Rey is a primary POV character, I think it's fair to say that it is a perspective TFA treats with significance- especially when factoring in Finn's reaction to the mention of Luke Skywalker, Han's "it's true, all of it" and the general nostalgia factor TFA leveraged in general. Poe was offscreen dead-not-dead for most of the movie so we didn't really get a chance for him to lend his perspective (but then he was already deep into he search for Luke and Lor-San Tekka under direction of Leia Organa, so he doesn't exactly have an everyday man's perspective of those figures/events at this point in time ether). The Threepio stuff here just seems to connect to that thematic material well. Binging through this arc and the last half year of SW issues, Marvel has been pretty good to Threepio lately, it seems. Not only is he amusing and gets a small-but-neat Vader connection moment but he gets this awesome droid spymaster plotline for a whole arc.
