He hadn't expected her to ask about his siring. He was caught off-guard momentarily, and said a few 'um's' and 'uh's' before he managed to tell her.
"I was co-sired. Kerr and Arles, who I don't... I mean," he frowned. Usually his response to this question was emotionless and easy. 'I don't remember' he would say, and if they asked why, he would usually turn his back on them and leave. He didn't want to be rude to Sam though, who was being quite candid with him about her own life. He didn't want to feel like the only thing he could do was walk away, so he explained himself.
"I only know what Kerr told me about it, because those memories were taken from me in some demonic ritual thing. I don't remember that either. Three years are gone, and in there somewhere I got sired. I was told it was okay, but I have no memory of Arles at all, I don't know what he looks like, and Kerr and I used to share blood all the time after I was sired, so his presence is pretty dull now."
He could still feel him though, far away, and it was weird to be connected to someone he didn't know, nor want to know. Thinking of Kerr was making him ache for his sire in a way he hadn't in a while lately. It was feeling fresh and raw again, because he'd been thinking about Kerr so much that it felt like his blood bond had reconnected. He needed to visit Penbrook. He was like a junkie, he supposed.
"I'm sorry, I have to go." He didn't, but he did. He felt bad for bailing on Sam when he really hadn't wanted to. Habits were hard to break, he supposed. He took a step back, not turning around to leave just yet without her permission.
