Tristan nodded. "It was part of the deal my father offered me. She got to come along, and he'd made arrangements for her to have a house." What the arrangements he'd made and who he'd made them with Tristan didn't know. Wasn't sure if he wanted to know really, that way he didn't know who the dirty dealers were in this game and he didn't get accused of doing business with the wrong family.
"I'm not sure you'd know her." He answered on that, not giving up her name or where to find them. He likely didn't know Rhiannon, so what harm did it do?
