What comes naturally

Trapped and close to panic Becky's adrenaline spikes triggering her natural reflexes and transforming her back into her slug form. The change is almost instant this time and she gives a surprised squeak as she falls the short distance to land back on her discarded clothes. By the time Mr Trent has finished pushing open the door she has borrowed under the pile, safely out of sight for the moment.

Mr Trent looks around the bathroom clearly confused. He sees the empty stalls, the pile of familiar looking clothes but he is more puzzled than alarmed until he sees her phone.

"Shit!" He curses "that can't be good."

He can think of a few scenarios where Becky might ditch her clothes and leave school grounds (admittedly all extremely out of character for the girl he knows but, still). But there is no possible explanation he can think of for any teenage girl to abandon her phone.

From her hiding place, Becky sees him heading for the door. He clearly intends to raise the alarm and she knows she has to act now if she doesn't want to end up on the evening news.
