"Okay. I was just wondering." This was an entirely new situation for Dexter. He wasn't sure at all how to comfort a girl who had panicked about you becoming a reaper.
Her anger and needing to drink was Deb territory, so he felt he could deal with that pretty well. He'd just do what he did for his sister. Keep supplying the alcohol until she either threw up and didn't want to drink anymore, or just passed out contentedly drunk.
"Would you like to have a seat? Or are you happy standing in the kitchen." He had no doubts that he could carry her. He'd already done it. But he really didn't want to see her fall and hurt herself, even if she could heal it.
"And would you like to talk?" It seemed like a good thing to ask.
