As far as he's seen, yeah - and the thing is, he does tend to bring out the worst in people like Tyki, with his belligerent, all guns blazing approach. Just as he did with Spike, at the time. Unfortunately, he has yet to learn that about himself.
He's grateful to Spike, though, for letting that slide and not forcing them both to rehash the same old arguments again, and he nods, giving him half a smile, and waits for the rest of it.
And does his best to actually listen, as well as he can. He has at least got a little better at that, lately, and it's obvious this is important to Spike. "Why don't you tell me?" he suggests, because frankly he was too furious with Tyki at the time to really get a feel for all this and left a lot of the responsibility of understanding it all to Kitty, who had far more experience of Tyki and the peculiarities of his condition.
