Star-Struck - S1.E31

The school is staging a musical called Teen Land. Pod 4 and the rest of the school tries out. Amelia is chosen as the lead, with Birch as her understudy. Zeke, a member of Amelia's pod, doesn't like the way she treats him and plots with Liam so that Birch can play the part. They lock her in the bathroom, but she pretends that there is a rat in the bathroom and when they come in to get it, she locks them in.

But because Birch is doing so well, Mr. Towes blocks her from coming back. When the whole thing is over, Amelia is very angry with Zeke for helping Pod 4 and chases him through the night.
