re: Rick Grimes is Baaack

The CRM appears to be sending Rick and the other consignees to defend Civic Republic territory from a small herd moving towards the community's crops. The zombies in said herd are on fire and a blazing building can be seen from the direction from which they are coming. The most logical explanation is that a fire occurred at a CRM food facility and attracted nearby zombies, which were then set alight but continued marching forward regardless. The zombies do not appear to be inherently aflame, meaning these are regular zombies that simply staggered too close to a fire, not fire-based variants. The CRM referring to the oncoming wave as "ignited" further supports this.
