Is it possible that George Lucas's original intent when creating Star Wars (Ep. IV A New Hope) was that Greedo was of a race that can regenerate fairly quickly? Is it possible that Han-shot-first because he knew it wouldn't kill Greedo, only stun him?
I'm asking because of this shot (appearing at 51:40 in Harmy's Despecialized Edition; so should match timing in VHS/LaserDisc versions):
This occurs 1 minute 38 seconds after Han shoots Greedo (film-time); given the events that occur, I'd estimate that 30-60 minutes have passed since Han shooting and the “Greedo-lookalike” roaming around the corridors of Mos Eisley. Is it possible that Greedo was just knocked-out while his mid-body organs (and clothes, apparently) regenerated? Or is it more feasible that others of Greedo's race (Rodian) were present in Mos Eisley, and wearing the same outfit?!
The later-Rodian looks to be wearing almost the same outfit as Greedo (though it might be a brown coarse-cotton vest with a pocket instead of the more silkly vest Greedo's seen wearing).
For comparison, 49:57 in the same version:
“It could've been a filming/editing continuity error” is not an acceptable answer because… no kidding. George slipped many other subtle details into ANH though, so I'm looking for something more real.
