I guess I don't understand her character yet and it'll all make sense later as it usually does in your comic. Though with the current pacing that's probably 2030 problem 🙃 (not complaining, I'm all here for it)

Sure but the person doing them already proved themselves to be a capable and accomplished engineer working with completely new and arcane things to the point of being noticed by Very Important People. Some level of disbelief - sure, but outright internal laughter and mocking?

It feels off how much she doesn't take him seriously. Isn't she aware that he literally created the TF gun and has years of experience with alien tech?
