For reasons unknown, the PR department for The Walking Dead is really pushing Michonne's new horse (a.k.a. Flame). Earlier this month, Entertainment Weekly put out a photo of the anti-zombie equine, and now AMC has released a horse-heavy season four clip. While the idea of slicing zombie heads at a full gallop is pretty cool, I suspect that AMC has signed an under-the-table sponsorship deal with HorseTrader.com.
Other, non-horse-related information we can glean from this new clip is that Rick and the gang still appear to be at the prison, and they've refortified since The Governor's attack. Also, they haven't mastered the art of getting in and out of the complex without being followed by a bunch of zombies. That said, if they did figure out how to do that, it would probably be a much more boring show.
The Walking Dead returns in October.
