When Amy's maternity leave is over, she returns to work at the hospital and, to her dismay, Karen is divorced and working as well. Amy starts having hallucinations of Charlie and Toby since she misses them so much. With both Amy and Bob working, Gabe and PJ are assigned to watch over Charlie, but things go awry when Charlie runs away. Meanwhile, Teddy attends the annual Student U.N. competition school debate alongside Victor (Kevin Covais). Toby nearly makes Teddy and Victor lose due to his constant crying. Luckily, the sound of music soothes him, so Teddy and Victor sing their final presentation, which leads them to victory. In the end, Amy becomes at stay-at-home mom, and Bob child-proofs all the locks so Charlie will not leave again.
