Are Carol’s days numbered… again?

In the first of two exclusive images from Sunday’s episode of The Walking Dead, titled “The Grove,” Tyreese is armed not only with a rifle but also with an “I ain’t messing around here!” glower. So maybe Karen’s killer should look for someplace safer to hang out than even Terminus?

Then again, the second picture is of a barbecued walker, so perhaps Tyreese only plans to use his gun (and his scowl) against zombies? Till we find out when AMC premieres the eppy Sunday at 9/8c, your speculation is welcome in the comments.
