She and Inkie Pie would travel into Ponyville or what remains of Canterlot to look for any survivors to bring back to their hideout or Pinkie's castle which was formerly Celestia's castle but after being slaughtered by the bakers, Pinkie Pie had taken it over as well as taken Celestia's role of raising the sun while Princess Luna had escape and is currently residing in The Crystal Empire with Princess Cadance and Flurry Heart so they could figure out a way on how to take down the bakers.
I imagine just like in the series, Babs look up to Inkie Pie but however, she sees her as her older sister.. oh and Babs is a lesbian because I said so, and no I don't ship her with Inkie because…ehh, age differences and it would just feel weird to me.
