Maybe, but she's still looking thoroughly amused regardless. Why he needs to feel so formal around her is something she's yet to understand, but perhaps where he comes from she holds herself more like a refined lady.

"I assure you Cas--John, I am no Lady. Formality is unnecessary. I hope I didn't give you that impression. Around Morgana it's hard to forget how to properly act around nobility, I admit."

Gwen takes notes of the discomfort the topic causes him and focuses her gaze back down on the weapons she's inspecting in hopes to alleviate that some. She can't help but feel a little guilty for asking him something that has bothered him. Once he begins explaining, however, she quickly ponders that from what she knows of it. Mercenaries hired by the King to keep the peace did a world of mucky work to keep the courtier's hands clean as well as the Knights'. But if not a knight what else is a man with his skillset to do? She can imagine such a dilemma is as true to his time as it is to hers, and that thought makes her worry for the long departed Lancelot.

"So your knowledge of weapons is no coincidence. Tell me, are they all like that-- What was it?-- tranquilizer gun you had before?"

Gwen chooses not to dwell on the details of his profession, as they both seem better off away from that subject.
