I was not expecting Tyresse to go and am sort of dissappointed as I thought he was one of the more interesting characters.
I have to confess that I was afraid from the very first episode that Tyreese is next one to go. I just didn't knew it was going to come so fast after we lost Beth in that last one. I still loved seeing her, Lizzie & Mika and the Governor in the episode. They added some chilling spice to his struggle, and I agree with Mrs Ctg that his effort was a worth of an Emmy.
He has been good, strong and stable character in Rick's Posse. I say Posse because to an innocent viewer some of their tactics might be a bit extreme. Especially since they got out from Terminus slaughterhouse. But I hope they'll start to see the way Michonne is showing to them by agreeing that Eugene was somewhat right, Washington DC is one of most probable places of finding other people. More probably than Atlanta with all its flaws and benefits. And I think Rick knows in his mind that if he's going to say no, it has to be for a good reason or otherwise he can say goodbye to most of his group.
What they need is a place to stay, but where they can find one when all known locations has been overrun one way or another by zombies. They can be seen as slow moving but when they pack together to create a horde there's very little anyone can do to stop them. Rick's posse doesn't have ammo or the numbers to take them down, but if they find survivors in the nation's capital then it's all good. They can breath easily and trust that they're safe, even if there's roamers on the street. The problem however is: how to get there?
How to get there safely I mean, because if you look the map, you'll see heavily urbanised areas all along northern Atlantic coast-line, and it doesn't stop until Canada's wilderness sets in. And that means a lot of potential zombies. Probably close to two to three hundred million individuals. But what is good for them is that mostly those one are slowly migrating to somewhere else, where that is, and what is the final size of the largest horde is going to be interesting thing to find out - if we ever get there.
Hopefully the spinoff is going to give some answers.
