Great episode, I don't know if it's just me getting my fix after having no WA for two weeks, but did this episode seem a load more exciting than the entire last chapter. OK my views:
Definately Angel who has the MP5. However, I'm pretty certain Pippin was killed with the pistol for two reasons: 1. Sounds different to when michael used it 2. It's missing from Burts/Sauls bag - can't be a coincidence.
I agree with Ra1th about the Burt from the future, because the episode starts with them locking themselves in a room. It is possible that he could have written it in this time, starting with what just happened, and then remembering to recap on what happened since he last wrote.
Another point is that the 'army' are carrying dead and/or alive bodies with them: Bricks/Tardust/Lizzy/Saul perhaps?
Randy. I reckon Michael met him in water pumping station, but I am curious to know if Michael knew him before this all started, or could it be a Datu/Samantha situation. lol
Also interested to see if Tanya had actually found a discrepancy with the journals, like is mentioned in the voodoo lounge.
Zombies surrounding the tower. Could this be a way to stop them sending reinforcements to help the 4 who have gone in? At first I was thinking it might all be one trap to catch some of the survivors, but 3 skinny and one flabby human won't feed all them. It got me thinking about the long term plans for the zombies. I mean since they are definately organised, what are they gonna do when all the food runs out? Start farming for vegetables?
Also with the mass rallying of zombies, are Victor, pegs and datu gonna be okay. Victor may be good, but hes not good enough to take on a few hundred. I would have to lol if pegs saved there lives by flying them out of there.

Wow now thats out of my system, just gotta wait another week til the next one.
