This is something that I noticed in last week's episode. For anyone who doesn't know who Jeanette is, check it here:

Since we didn't see her on the bus that Maggie, Sasha and Bob found, and Sherry Richards didn't come for filming in this episode, there's a chance that Jeanette had escaped the bus

In "Us", when Glenn and Tara went into the tunnel, I noticed that this walker kinda looks like Jeanette, is it she?
