We’ve now given you nearly 48 extra hours to watch the most recent episode of The Walking Dead before posting these videos, but if you haven’t seen it yet, go read something else on SciFi Mafia and don’t come back to this post until you’ve watched that episode. Episode 304, “Killer Within.” Go on, now.

Okay, presumably you have now seen that episode and won’t be spoiled by this post. What. An. Episode. We’re still reeling, over here at SciFi Mafia. To help us deal, we are posting a special featurette and a bonus clip before the upcoming weekend’s usual round of The Walking Dead videos. The first is by composer extraordinaire Bear McCreary, about the work he did on the last act of the episode.

Next is an online-only bonus clip from Talking Dead, the weekly “after show” that follows the first replay of The Walking Dead on AMC, hosted by The Nerdist‘s Chris Hardwick. Last week’s broadcast episode was terrific, do try to catch it if you haven’t already. But this is a clip that wasn’t aired, that includes additional discussion with his guests, The Walking Dead‘s executive producer Gale Anne Hurd and T-Dog himself, IronE Singleton.
