Andrew Lincoln, Chandler Riggs

When The Walking Dead returns from its midseason hiatus on Feb. 9, one of the biggest looming questions is what's next for Rick (Andrew Lincoln) and Carl (Chandler Riggs)?

A new poster for the second half of Season 4, which AMC released Thursday, puts Carl front and center as he and his dad walk along  train tracks with the tagline "Don't Look Back." In the wake of The Governor's (David Morrissey) assault on the prison in the midseason finale, it remains unclear just how many people are still alive. 

But even with The Governor no longer a direct threat, Rick and his son still find themselves in survival mode. "Rick and Carl are out on their own, they're by themselves with no supplies and no sanctuary," executive producer Robert Kirkman told TVGuide.com last month."They're definitely in the most dangerous position that they've been in yet."

The Walking Dead returns Sunday, Feb. 9 at 9/8c on AMC. Check out the poster below:
