On one normal day whilst during her rounds, Nerys made her to Lord Wobblebury's castle, but accidentally called in at Castle Frank N. Stein on the way. Slamming her way through the front door, she instantly believed Chuck D. Head to be her patient and pushed him into a chair, falsely reassuring him. Before Chuck could protest otherwise, Nerys had ripped out a perfectly functional tooth, used a large drill to create a filling and mixed up some cement to close up Chuck's mouth. The commotion awoke Professor Frank N. Stein, with Nerys unsure of who he was. When informed she was in the wrong valley, Nerys left without another thought.
