The Walking Dead: Who's Blood Was Dripping?

Spoilers follow from tonight's episode of The Walking Dead (season 6, episode 5), titled, "Now."

At the end of the episode, following Rick and Jessie's romantic moment (finally!), Deanna seems to have gone a little haywire, banging on the fence, teasing the zombies on the other side of the gate.

As she walked along the wall afterwards, blood appeared to be dripping from the top of the panel. Who's blood was it though? Assuming it was truly dripping, and not beginning to come through the wall, the set up seems to have been for the blood to have been Deanna's son, Spencer's.

Spencer was last seen relieving Rosita from her post atop the wall and was previously seen acting quite reckless and even getting drunk. Perhaps those potato chips he decided to eat after Rosita left him there were a last hooray before killing himself.

Other possibility, a Wolf killed him atop the wall and left him there or a mole inside Alexandria did so for the Wolves.

What do you think?

The Walking Dead airs Sundays at 9 PM ET on AMC.
