Giles is definitely, very definitely, the one in need of comfort, following apocalypse-prevention which caused him some overall stress. He'll be comforted by meandering conversation, with side orders of tea, cuddling, and love. (There might also be some warm blankets.) Buffy is the one mainly doing the comforting, and it's a shippy sort of comforting, but the rest of the Scoobies are there too, because Giles is their bestest bud.
Harrumph. Now to figure out when to set it.
