I do not quite know how it happened (and she would never tell). One moment she was tinkering around with something and then suddenly there were flames licking along the side of the wall, and a nun shreiking and fire alarms and it was great. And afterwards she would have a secret smile on her face about it, and they could never expel her because nothing could be proven despite all the times she was called to see the principal.

I just really hope the world was kind to her because SHE BURNED DOWN OUR LAB.
