AMC has released the character descriptions for Season 4 of The Walking Dead, and they contain a couple hints at what the future has in store for several characters. With Rick still recovering from the death of Lori, it looks like Daryl will have the chance to step up into more of a leadership role. Of course, Daryl is also struggling with the loss of his brother Merle, so there are questions over if Daryl will be able to rise to the occasion. In one of the Season 4 preview trailers, Tyreese was shown kissing the hand of Karen, which had us speculating that the two might be a couple. The official AMC character descriptions for Season 4 confirm that there is definitely a relationship brewing between Tyreese and Karen. However, the character description for Karen notes that even though she is teaching Tyreese "what love means," she is reluctant to use the term "boyfriend." Check out the full character descriptions for Season 4 below. RICK GRIMES - Rick is slowly recovering from the loss of his wife.
