Tristan allows the others to answer first. Roach'd included them in the question, after all. He doesn't dig too deeply into the exchange, either. For the most part, anything Val or Emily have to say are repeats from previous conversations. All he really picks up on is Roach's somewhat standoffish nature and Val's unfailing need to push the envelope.
Her shift back to human shape is just the latest in the line of... slights? No, not slights. This fellow Half-Moon is probably just trying to get a rise out of them. That's what shrinks do, isn't it?
The three females bounce their conversation back and forth, and Tristan frowns as he tries to get a word in. The moment for it doesn't come, though. Emily's asked them a decent question. Twice, now.
"Right." he finally rumbles. "Roach, you've just blown through town and... Dr. Queen? You planning on going back to these kids of yours?"
