Sam saw the girl was lying, but did not say anything about it. Instead, he began talking about her armor. "That's good. By the way, can I just say I love your armor? It uses a *insert technical stuff here*, right? Personally I would use a *insert even more technical stuff here*, but as they are pretty expensive, I get you choose these." He said. If the girl made the armor herself, she should be pretty intelligent like him, and they could start a conversation to buy some time.
