The nacelles were damaged? How do you know THAT?
Umm, what? It's you trying to prove that the ship was propulsively crippled and needed Jaylah's attentions to cease being so. Damage to nacelles is what one would traditionally associate with a putative crippling of the warp drive, and my argument is that Jaylah probably couldn't have done much if anything about damage to those bits.
Jaylah could, with Scotty's help. That, too, is more than could be said for you and me.
We don't really hear of Jaylah making the ship fly. After all, she asks Scotty to do that for her instead. And we don't hear or see Scotty doing anything more than having a quick look and declaring the ship flightworthy, with the caveat of those EPS bits missing and the complications on takeoff.
Sure, we can argue the ship was in pieces and these two put the pieces together. But we can also argue the opposite, taking into account
1) that Jaylah would have lacked the means and most probably the skill
2) that Scotty would have lacked the time
3) that there's no sign of the ship actually being hurt much in the first place and
4) that there are plenty of other reasons for Edison to fail to fly home with the
Franklin, considering that he had numerous other spacecraft (indeed, a whole screen-filling swarm of them!) to choose from and chose none.
What the Christ? This is so dismissive and, honestly, sexist as hell.
Please refrain from bringing religion and sexism to a so far religion- and gender-neutral discussion. Or if you absolutely must define Jaylah by her boobs rather than her plot-demonstrated abilities and limitations, then please refrain from applying a double standard on what can be discussed and what not.
