Hidden dangers
Without the Host Attire to help him control himself, it took his entire being to stop himself from tumbling when he heard the lady's question. Was he married? He just used dragon aura to intimidate the hell out of them all, but instead of getting scared, the woman started head hunting a husband for her daughter? Hopefully her daughter.
Regardless of her intentions, Lex only replied with a smile and said nothing. He was not about to fall into this trap. If he engaged in this conversation, he was done for. Whether he accepted or denied it, he would have entered her web. The only way to avoid the whole situation was to just ignore the question, as many times as it came up. For if it had been mentioned once, he had a feeling it would be brought up again.
