If the Saviors know every route they might take to Hilltop, doesn’t that mean that they probably know where Alexandria is?
They do. Dwight said they’d been watching it.
Other than a Savior mentioning Alexandria at one point
the Saviors knew where Hilltop is located. All they would need
to do is go to Hilltop and branch out to cover all routes.
However, I missed whatever it was that clued the Saviors into
the fact that Alexandria folks were heading to Hilltop in
the first place.
As to your earlier question, Carl no longer has a right eye.
He only has a part of an eye socket. He needs to hoof it
back to the prison to recover the one used by the Gov.
