Well, had LF wanted to have that kind of “OT Han” I described, they would’ve just written the scene differently: he might’ve been cornered rather than surrounded, with the two factions in front of him or at his sides. Then he could’ve used the right timing to reach for a door behind him and so on.
Again, I’m not saying they should’ve done this, just that, if they wanted to, they could’ve done it. I guess they were more for a comedy scene than for character consistency, which is something not everyone liked (including myself), but it’s not a crime either.
