Gaius' smile was helping a little, even if it was forced. Nimue really wasn't sure what to expect, but the smile was a great deal like Merlin's. That was comforting, at least. If he had that much of Merlin in him, he was likely a good person.
Melora popped up. "Hey, I can get the tea, no problem." Merlin and Nimue staying seated was a good thing. "Could be worse, right? I could've come along to tell you that I'm pregnant with his kid and you're going to be grandparents! Not true, though. Just a friend. Moral support, and all."
Nimue raised an eye brow at Melora, but reached out to put a hand on Merlin's. "Teaching?" She smiled a bit. It would be just a little amusing if Merlin ended up in a class taught by his son.
