It's that time again! AMC's 'The Walking Dead' prepares to unleash its biggest episode yet this Sunday with season 3 finale "Welcome to the Tombs," and the latest round of photos from the episode suggest Rick isn't all there as the Governor and his men mount up for their final assault. Will Rick be able to pull it together, if only for Carl's sake? Find out in the latest 'Walking Dead' season 3 finale photos inside!

Viewers won't soon forget this coming Sunday's all-new episode of 'The Walking Dead,' as Woodbury's Governor and the prison survivors finally face off in season 3 finale "Welcome to the Tombs." Courtesy of Zap2It and AMC, we've observed yet another round of photos that predict a dire outcome for the prison, as the stress of defending his group seems to weigh heavily on Rick once more.

Elsewhere in Woodbury, the Governor rallies his men to the cause, but it's clear Tyreese ('The Wire's Chad Coleman) and his sister Sasha aren't as fully on board as their former traveling companion Allen, who lost his son to stray gunfire in last week's "This Sorrowful Life." Will Tyreese and his sister have a change of loyalty before the hour is out, or are Rick and his surrogate family truly welcomed to the tombs?
