Barbara stood there for a moment, mouth agape as Cass shouted her head off at her and then ran away. It didn't matter that the girl hadn't hurled any expletives at her--she might as well have for as furious as she had been. Babs was tempted to run after her, but it probably wasn't a good idea with the girl so geared up. Bruce would be able to talk her down--Bruce or any of the others really, and then Barbara would sit her down and explain the whole situation to her.
She sighed, shooting up a grapple line and heading back towards Clocktower. All the fight was drained out of her for the night.
