The Walking Dead Episode 16 "Welcome To The Tombs" Spoiler Pictures

In the photos above we see one of the guard towers on the prison grounds. In the promo we see Martinez launch a grenade into the first one and I would imagine if he did it to one he'd do it to them all. They don't seem to be inhabited by any one from Rick's gang. Rick and his group are smart enough not to leave one of their members vulnerable in a tower a hundred yards away from any one else. Also we see a tube that is probably used to make it appear as if Martinez actually shot a grenade in their. This tells us that its not digitally created and they have one shot at the filming. 

In this photo we see Rick and Carl outside of cell block C. Rick appears to be giving him a well needed pep talk. My prediction is that Carl wants to join his father and whoever else will be accompanying him to attack or scout out Woodbury. Rick of course will not agree, unless Carl can give him a valid reason. This should be a scene that will show how much parenting Carl has lacked because of the apocalypse.

In the photos above we see Michonne, Daryl, and Carol  conversating, more than likely about there attack on Woodbury. I couldn't see Carol going, but she's probably talking to him about Merle and wishing him safety in his Woodbury attack. I would imagine Michonne, Daryl, Rick and Glenn or Maggie to attack The Governor at Woodbury. I think they would leave either Glenn or Maggie to protect the prison, should The Governor attack.

This photo, judging from the look on his face, shows Rick caught between a rock and a hard spot. This is either before a tough father-son talk or after a failed one. We can also observe the door in the Ford truck is open, which leads me to believe Rick is close to departing from the safety of the prison.

The photo above is a tweet from Melissa Ponzio (the actor who plays as Karen) that was posted about her role as Karen. My theory is not confirmed I'm going by the tweet above. She says she "hopes" for her character to become, key word become, as tough as Martinez, which tells me that she will not die in the finale. I'm hoping she will kill The Governor as Lily did in the comics. For those who don't know, Lily was only mentioned once in the comics, as Karen has been a very minor character at Woodbury. Will she kill The Governor? I sure hope so!

In the photo above we see The Governor with a dangerous look on his face. Judging from the background they look to be inside, or close to Woodbury. He seems to be attempting to get his people in the right mind set, probably yelling and screaming at them about how terrible Rick and his people are.
