-Do we see the "wolves"?
No, but Daryl and Aaron find a cut up walker, only its torso is missing. They find a woman tied to a tree, nude, guts hanging out with a W cut into its head. There are also two other walkers at separate points with the same W on its head.
-Does Tara die from her head injury?
Tara is apparently 'stable'. Nothing more about her.
-Who is Sasha shooting at?
She shoots a lot of walkers. Some are walkers in the woods because she wants to attack instead of defend. She shoots some that are banging on the walls of the community.
-Why is Enid running?
Carl and Enid are chasing on another through the woods in a playful way.
-Do we find out more about Enid and what her story is?
Carl asks but she won't tell. All we know is that her mom is likely dead as she has her knife.
-Does Rick find out about Gabriel telling Deanna they are bad?
Not at the moment. Gabriel is not in the episode.
