Like so many of us...she forgot to take her charger.

just don't be surprised when you see a chick with her ass plugged into an EV car charger @ a parking lot.
"nothing to see here" she'd say. "nothing at all"

I don't think that's an issue. The first thing she does after leaving the compound is to call in the chopper. The chopper pilot is going to fly her to wherever she wants to go. Upon landing there, she will rip the pilot's head off, and hook onto the chopper's battery. Then she'll go on and find another victim. She's so super-intelligent that I think in no time she'll be able to get a place to stay, a car and possibly a job, which will take care of her energy needs. She may even hack into computer systems, and build her own army of robots, like Skynet, and pursue world domination, who knows. There are endless possibilities for a superior mecha-being like her.
