If some purple-haired boy a decade her junior wanted to act like he understood better than she did what she was up against, she didn't need to argue with him. She knew all that, after all, and it wasn't making her learning how to do this any easier.

If you wanna talk shop, though, c'mon over and have a look for yourself." She waved him into the currently otherwise empty target range, hefting the gun for him to examine if he wanted to.
