If Rick were like this in every episode, I'd have no issue with how they're handling the character.
LOVED the scene with him and Herschel at the end.
I am also glad he saw through the Governor's bullshit, and I completely understand why the character had to leave out the part about trading Michonne. If Rick tells them about the Governor's proposal, then half the group (if not more) would be happy to send her off, and after what she's done for the group that would not be fair. Also, where does it stop? What if somebody else pisses off the Governor? Do they give that person up next? Then one at a time, the Governor whittles them away. It's no different from a straight surrender. There is no 'agreement' between them because you can't hold the Governor to his end of the bargain. Rick saw through it all and I am so glad he found his brain.
Andrea's in a tough spot right now. After all the times the Governor's frozen her out of knowledge and meetings, she should clearly be able to see the writing on the wall. But for Andrea, it's not so simple. It's not like she really spent all that much time with Rick's crew. She spent more time with Michonne than she did with any of them, given the passage of time between seasons two and three. Also, in her head, Woodbury represents the best return to civilization. Electricity, hot water, community, jobs, order and structure. It would be hard to walk away from it a second time just to live with nice people out in the sticks. Some people just don't want to go back to a hunter-gatherer lifestyle after getting away from it.
I got no problems with Andrea as a character right now. She's well written for the most part.
I am afraid that Merle is going to be this show's version of Sawyer from LOST. He'll become really popular and they'll start overexposing him. Shows need to realize that less is more with characters like this. Let him be the guy making all the noise and bringing all the fire. That's his role. Let him stick with it. In fact, I'd almost rather they killed him before they ruin him.
And please, please, please. No Negan just yet. Going from one ruthless warlord to another would just be redundant. I'm more looking forward to the prison battle and the aftermath. The entire next season should focus on the aftermath of the prison battle, IMO.
