You're missing the batshit insane explanation. Angel's hired the tailor and is hallucinating what he's saying, the way he's hallucinating the bird talking. What's driving the hallucination is anybody's guess, but that's my story for the moment. That's my explanation for why we have the panel of Angel being told to make a costume by the guy Angel's already hired to make the costume.

Doesn't mean that can't be Spike's ship. But I like the idea of him sailing to Scotland. (He's too late, of course, the castle is already blown up -- but he doesn't know that. And I like the very neat trick of explaining in one panel without words why it is that Spike hasn't showed up until now. By the time he got on the trail, Buffy was already in hiding).
