Clarissa uses most of the remaining Air elixir to combat Davoust and push it outside herself. She uses the fumes to sprint away, outpacing the dogs and remaining Servants. She does not kill the Davoust/Elemental creature though, only knocks her back and stuns her long enough to get away.
I want some kind of unreality here, like the bathroom scene in The Conversation. Does she see the world like Neo for a moment? Pure element instead of the code for the Matrix?
