Who are those tall guys on the big woolly mammoths? Is it really true that members of the Night's Watch can have sex? Is it true that Maester Aemon could have been the king?

As withthe rest of this season to this point, we've put together a list of scenes, references, and characters that deserve a special comment or mention. There's no way we got all the good stuff (and we might be wrong on some of the things we've left below)—so please help expand our appendix.

(It's a short list this week, because not much happened that required explanation or annotation—but please, if I missed anything, add it in!)
