I like the escaping idea, but that is the kind of day I had. 

Let me recast Alexa a bit. I could see Alexa being a bit like Q(from James Bond) making magical gadgets for them with the changes. Unlike Q, her stuff could have side effects or quirks. I am not seeing her as a high combat character. Her idea of a job is get in, get it, get out without being seen. Something that rarely happens.
