The Walking Dead sneak peeks are usually nondescript and even confusing at times, but the second blurb we got for next Sunday’s Episode 14: “The Grove” is just plain creepy. From the promo and sneak peek we’ve peeped so far we know they ep will follow Carol Peletier (Melissa McBride), Tyreese (Chad Coleman), Lizzie (Brighton Sharbino), Mika (Kyla Kenedy) and baby Judith, and this sneak peek seems to reinforce that, but we can’t be quite sure just yet.

The clip begins with a song playing on the radio. The camera then pans out and to the left to reveal a teapot on the stove and what looks like little jars of baby food on the table as a child (maybe one of the older girls) can be heard fussing in the background.

The more interesting thing however, is what’s going on outside of the house. The camera turns our attention towards the window, through which we can see a young girl who looks an awful lot like Lizzie playing tag with a walker, running and laughing. Given Lizzie’s track record of bizarre behavior with walkers, this actually makes perfect sense. But what exactly are we watching here? Have Carol and Tyreese decided to play house with the kids? Are we watching a flashback of some kind? We’ll have to wait until next Sunday to find out, but tell us your thoughts and theories below!

The Walking Dead Season 4 airs Sundays at 9 p.m. ET on AMC.
