Tara has been stuck in the background for several seasons now. Her closest relationships in the Survivors group were with Glenn, Abe, and Rosita. Glenn and Abe are gone. She did get a chance to shine in “Swear”. But that might indicate that story arc is coming to a close.
But the fact that she’s remained a background character for so long could also mean that now she’s going to get a fuller story arc.
The Survivors ranks have been depleted over the last couple of seasons. That could give characters that have been on the fringes of the group more opportunities to take on bigger roles in the Survivors group.
Now that the communities are going to come together and fight Negan Tara could finally get a chance to become a more developed character.
She has good fighting skills and she’s brave. Alexandria is going to need fighters. Losing Glenn and Abe hurt the group physically as well as emotionally because they were both great fighters.
Tara probably has a 50/50 chance of making it through Season 7. She could be a huge asset to the Survivors if they win the war.
If they do win they will still lose some of their fighters and Alexandria is going to need to be overhauled, resupplied, and possibly rebuilt. Hopefully Tara will make it through and take a place as one of the main Survivors in Alexandria.
