"Not if they didn't get the brain. That's all you need." Considering how many walkers she's seen who are falling apart, there's no reason to hope a dead skull with an intact brain would escape that fate. I'm sorry we left you that way, Daddy. "Sometimes it takes an hour or two. We have to find the corpse."

Nobody's freaking out here, which says they still have time. She kind of doubts everything would be so calm if a grey-skinned monster had woken while somebody sliced off its hair. (Which is incredibly gross, by the way, but they don't have time to ponder just how gross right now.)

"So if they take the scalp. What then? Do you burn them or leave them out for the animals or what?" She's getting up as she asks. As loath as she is to leave the scant warmth of the tent, they need to find those remains. "We should probably get it away from camp--just to be safe."
