PJ and Gabe suspect that their neighbor Mrs. Dabney has killed her husband, Mr. Dabney, and they try to find evidence to prove it while babysitting Charlie. Meanwhile, Teddy becomes jealous that her best friend Ivy has become texting buddies with Amy, which Teddy thinks is lame. So Teddy decides to spend time with Ivy's mother, Mary Lou Wentz, who turns out to be unexciting and very boring, and Teddy learns that Amy is not as lame as she originally thought.
