"Burden?" Xander repeats that word, more out of surprise than anything. A burden? It's always a shock to him when someone insists they're a burden. Alex. Seto. There have been others, and now Siebren joins them.

He has to protest. "You are not a burden! Confused and scared, maybe, but we all are at some point! I was before I entered this room, but you guys--my family--supported me, and I'll be damned if I don't do the same!"

Xander moves out of his seat, to kneel on the floor before Siebren and gaze up at his face. "Dad. Dad. Seto and I are here for you. We're not going to leave you alone. No matter what. I--I killed a demon for Camael, once. If I have to do the same for you--I-I'll do it."

That, too, is scratching the barest surface, but if they want actual details, he'll share them. They're family. They deserve nothing less.
