She has no fusion core in her power armor, thought that pickpocket it would be serious fun.
See how it would look then she exited the power armor.
And she don't have any

I slaughtered most of the wasteland and burned covenant to the ground...but c'mon man....taking the fusion core out of a hard working woman's armor that she uses to move around...that's cold.

Poor Ingram! Stealing that core would be like taking the wheels of a wheelchair, low blow.

I'm glad I'm not the only one who tried this
