AMC has revealed two new images from the upcoming midseason premiere of The Walking Dead, titled "After," featuring Rick and Carl Grimes, now separated from the group, and Michonne, who has two new undead companions in tow. Here's the official description for the second half of the hit drama's fourth season:

Following the devastating events of the midseason finale, Rick and the group are still reeling from the loss of their home, family, and friends. With the destruction of the prison, we see the group of survivors broken apart and sent on divergent paths, unsure of everyone else's fate. What was a challenging life behind fences and walls grows that much more perilous and precious as they are exposed to new dangers, new enemies, and heartbreaking choices. They will have their faith thoroughly tested -- a faith that breaks some of them and redeems others.

The Walking Dead returns Sunday, Feb. 9 at 9 p.m. ET/PT on AMC.
