She's fumbling her way through pretty much every scenario in the entire movie.
- She wins the fight against the dudes who were trying to steal BB-8, but for a quick moment we almost believe that Finn was gonna need to step in to save her.
- She struggles to get her bearings when first flying the Falcon. The movie even goes so far as to literally handicap her by not giving her a co-pilot, symbolically establishing limitations to her skills.
- She fucks up with the fuses on Han's freighter, setting the Rathtars loose and almost killing everyone.
- She talks multiple times about just wanting to get BB-8 to the Resistance, then she'll go on her merry way back to Jakku and not get involved. This is a really consistent theme for her leading up to the moment where she refuses the lightsaber.
- She gets herself spotted in the woods on Takodana when the First Order arrives by being super cocksure and shooting a bunch of Stormtroopers, which draws them to her, even though she was already pretty well hidden.
- Kylo manhandles her pretty badly during their first encounter, literally paralyzing her.
- During her duel, Kylo literally backs her up to a cliff and remarks that she needs a teacher, which tells us how much skill she was exhibiting up to that point. She only wins because she lets the Force take over, which was first established as a guaranteed insta-win strategy in Episode IV.
