I like to discuss this stuff, too. I guess I have to withdraw my "no character development" discussion because that's all I've talked about. In regards to Tyrese's actions, I feel that I don't have to defend them at all, it's not my character, it's his. If it were me with some asshat that tried to kill a baby, I'd have him disemboweled in a couple of seconds. But Tyrese isn't me nor you, and so his actions are his own (within, obviously, the Walking Dead world) - and so far he is actually staying "in-character". He's playing the big softy right now, and it works, although I'm curious if they will put him in a situation where he has to kill humans, and at that point, when he reverts back - people better watch out, 'cause that guy is huge.
If you will recall the conversation that Tyrese and Martin had in the cabin before Martin escaped. Martin was basically outlining the us/them attitude that Tyrese has - so the justification of his actions is all there.
They were all walking around in the water after the shelves went down, so it was just bad luck that it was Bob that got attacked (and I still think bit, but we'll have to see). I agree about the foreshadowing, he was fucked from the get go on that.I thought it was stupid how he got attacked/ bitten by the pool Zombie (Do you mean with "past" the last episode? Sorry English is not my native language and I try to improve it ). They knew that some Zombies were under water because they dropped a shelf on them and you could see the bubbles. Isn't that like first chapter in Zombie Survival guide 101? And you have to agree that they really foreshadowed that something will happen to Bob because of his optimism.
I also just love the multiple plot lines going right now. We have the car that flew by that Carol and Daryl are chasing, we've got Galeth and his Terminus bunch, we've got Gabriel and whatever the fuck he did, and finally that guy that we got just a glimpse of at the end of the first season. So much awesomeness!
(and your english is fantastic)
