[It's not the first time Rebecca's been treated to all the lights in the dome going dark on her, though last time it was relatively peaceful. Which is why she didn't think twice about gathering a bag of things by candle light, and leaving her apartment with a flashlight for supplies before hoping to head to HQ to check in. But then she got wind of the chills and had an unfortunately timed run in with a clawed, toothy thing that went bump in the night.
She really didn't have any hope of killing it with only one arm while holding a flashlight and then no light and two arms when it bowled her over, so her main priority was fleeing. There were a few snags in that plan, which included losing her headphones slash communicator to the chomping jaws. But she kicked her way free and fled, seeking refuge in one of the storefronts to nurse various scratches, a bleeding forearm and a good smattering of bruises.
Chances are she'll stay there for a bit before braving the dark again with her cracked, now flickering flashlight.]
