With Sean's tirade Sarah was feeling rather small. She also saw Sean's fist coming around to connect with her face probably. She couldn't believe that one, he would have the gall to confront her like this after she just showed her power, two that Sean, who was normally a rather soft spoken guy, had the capability to display this kind of outburst, and three that he was actually going to HIT her!
"You're no bigger than a mouse really, are you? You ARE a mouse!" As she spoke, Sean's fist came closer and closer and then a purple beam of light shot out of the ray gun and hit her square in the chest. She immediately began to shrink as fur began to sprout from her skin in various places. She felt tugging in parts of her body, particularly her ears and the top of her butt.
Sean's fist continued as Jon and Karyn watched the scene unfold, and Sarah's rapidly shrinking form seemed to "duck" just in time to avoid his fist. The momentum of his swinging fist twisted him around and he took a step back. Karyn's wish was apparently fulfilled and Sean was no longer compelled to yell at Sarah like a drill sergeant, so he backed away from her until he got back to his seat.
Meanwhile Sarah had shrunk down to the size of a mouse, about 3 inches tall and was buried under her clothes. She started screaming but the screams came out as small squeaks. Scuttling out from under her pile of clothes, Sarah twisted around and looked at her new body. She was a mouse! And worse (in her warped mind anyway) she realized that she had pointed the ray gun at herself instead of at Sean. "Oh my god! I did this to myself!" she squeaked.
