Countdown to Armageddon
Nah Im pretty sure BTT been part of the D-team from jumpNot a great episode but I wasn't mad at it. They gotta devote some time to building up the Alexandria characters, otherwise why would the audience care about them when they are later in more trouble with these Walkers?
Keep in mind that Tara, Abraham, Eugene, Rosita, Gabriel and others were once considered the B-Team as well...but they spent time establishing/building their characters in filler episodes.
