I wish to call your attention to scans from the latest issue of the Buffy comic, which, as you must know by now, finally features Giles. Specifically, note this page. They were of course on that street because they popped upstairs to call upon Giles moments after the events depicted. And then... what happened? Tell me, please.
(I get my copies by subscription and I haven't gotten mine yet. Am on fire, of course.)
