Pushing up to her feet, Hermione ran after them and pointed her wand, screaming "STUPEFY!" at the witch.  The jet of red light hit Bellatrix in chest and froze her. Hermione exhaled, watching as the witch rocked, like a statue that had been knocked into, before she she began to tip backwards towards the bell jar with the hummingbird egg they’d seen coming through. The humming bird had already reformed back in its loop, returning to the egg when Hermione watched as  Bellatrix’s head sunk through the jar, as if it were a soap bubble, and floated amongst its contents of the glittering wind.
