Hmm, I don’t know. I think there’s no real continuity issue, as Finn can approach the other two from offscreen easily in that timeframe. Apologies because I can’t remember who off the dome, but someone has the idea to add a few faint footstep sounds to imply Finn is walking over even. The clip you posted, and granted that I’m watching with a hawk eye, feels edited as the dialogue doesn’t match their mouths, especially Rey calling out Poe’s name.
I dunno, I think what we got so far is probably as good as that little scene is going to get.
Does the walking sound help? I couldn’t see I’d there’s better sound clips.
