You're really cramping his style here, ghost mom. Chase sighs and rolls his eyes, as if he's so inconvenienced by the fact that Caleb's paying attention to his dead mother instead of him. He'd turn the tables and hold a conversation with Mr. Danvers, but... it's too unnerving, to be honest. Caleb's not wrong in his assumption that Chase's father was in pretty much the same state, though a bit more, uh. Animated than William Danvers the Third or Fourth or whatever. He was freaking chatty (must run in the family). Thankfully, though, that old man's nowhere to be seen among the ghosts.

Even in death, he can't be bothered to give a damn about his son. Which is fine, because mother dearest here is making Chase uncomfortable enough. Especially when Caleb assumes she's his sister, because it just reminds him of how young she was. Hell, it now hits him that he's the same age now that she was when he was born.

So he keeps his attention on Caleb, opting to ignore both of the ghosts. "Not a sister. I'm an only child." And that's all he's going to say, so you can put those eyebrows down, Caleb.
