"Oh, maybe you should-" not drink it all at once, Wren starts to say as the girl downs the vial in one sitting. Too late for that, though. There it goes. Already, Wren can see the potion taking effect, watching with a mix of concern and bemusement as Terry slowly starts losing height. Oh well, maybe she can have fun with it while it lasts. No use letting a potion like that go to waste, after all.

"You'll know once you notice it," is all Wren decides to say, leaning on her elbows back over on the counter. This is why she lets people have a taste first- their inevitable surprise is payment enough.
