Ellen realizes the time on the wall clock is wrong after Rick points out Amanda has been practicing on the clock. Rick shows Ellen the time on his wrist watch. Ellen tells Amanda she should reset the clock when she's done practicing. Immediately Amanda tries to reset the clock, but the only problem is she doesn't know what the exact time is. She does, however, know by how much she changed the time, so as long as the click has continued to run, she only needs to precisely reverse her previous change.
