Piper (to Bianca): Hey! Future girl!
(Piper throws the vial at her. An athame appears in Bianca's hand, she hurls it at the vial and shimmers out. The athame breaks the vial mid-air on its path to Piper. Piper freezes the athame just as Bianca shimmers in front of Piper. She picks the athame out of the air, turns around and holds it against Piper's neck)
Bianca: You were saying?
Phoebe: Wow. She is good.
