When she was gonna get hit by the truck, she had just gotten up and panicked.

When trying to run away from Roman... Well, he had been knocking her around for who knows how long, and using your Semblance probably takes Aura, so since her Aura had been reduced by falling several stories and getting punched out and kicked in the face and then kept low by Roman hitting her around, I don't think she had enough Aura to spare on using her Semblance.

Running from the Death Stalker and Nevermore, though, I can't figure out what the hell was wrong with her.
