You're looking for something that isn't there. It was just a badly written movie.

You're presuming that the empire wants her to survive

The loose ends aren't secret plot twists. They're just bad writing.

And what about her sister?

What sister?

Her sister died attacking First Order ships.

oh right at the start

Siblings dont have to support the same cause

dude stop

Just. Bad. Writing.

I cant remember, was that a story she was telling?

No, they spent several minutes focusing on the sister.

She mentioned if off hand at one point

cause what if it actually turned out.. that ter sister was on the death star or something

"killed by terrorists"

no they very clearly showed her dying

she was on the last bomber

but was that a scene... or was she telling the story and then it went into the scene?

no that was a scene

at this point you hadnt even met miss plumber comissar

ah yeah I remember... and then something about a necklace

thats it

unless... her sister was a spy too! 😛

cos their parents were on the death star

Literally the only plot hole that this fills in is the part where she crashes finn out of the way of the massive cannon

maybe kylo ren is her brother

That's not a plot hole. That was a conscious decision on the part of the writers.

Every male lead is stupid. Everything they do is pointless or downright wrong, and the female leads are meant to show them the error of their ways.

Finn, by trying to do something heroic and self-sacrificing, was wrong. The writers wanted that to be the lesson.

Yea im gonna consider that a plot hole

I refuse to believe that any studio could conciously decide that was a good idea for a movie

not sure if thats true... the feminist haired woman seemed fairly stubborn etc... but came through in the end

By a) not telling her subordinates what she was trying to do and b) breaking the SW universe.

Why didn't the rebels just evacuate a medical frigate and get a droid to crash it into the death star?

She assumed command and saw the discontent brewing amongst her crew

Instead of taking action to forestall it she chose to sit by and do nothing

Then at the end she made the wonderful decision to sacrifice herself, leaving the alliance without a fleet and without any leaders

But the important thing is that Poe was wrong about everything.

All that heroic stuff that we expect from dashing pilot male leads? Completely wrong.
