Shipnotized (Season 1, Episode 15)
When a famous hypnotist visits the SS Tipton, Bailey and London go to one of his shows. When he brings up a couple as volunteers and lulls them into a trance through his voice, London, unbeknownst to Bailey, gets caught in it too and is sent into a hypnotic sleep along with the volunteers. The hypnotist then gives the command to "act like the person next to you". While the couple act like each other, London also accepts the command, and after seeing that Bailey is next to her, her personality immediately changes into Bailey's, making her talk in a similar accent and using the exact same expressions as Bailey. Later that night, when London tries on Bailey's clothes and shows interest in farm activities, Bailey quickly figures out what happened and initially wants to undo it, but changes her mind after seeing that the farmgirl version of London is much nicer and less selfish than the real London. For the next few days, Bailey enjoys London having the exact same interests as her, but eventually hits a breaking point when London takes it over the top, hogtieing Bailey with a rope and incessantly talking about abstract farm topics, ironically giving Bailey a bit of an understanding as to why London finds her annoying. After trying to snap London out of her new mindset herself and failing, Bailey drags London off to the hypnotist. When they get there, said man is hypnotizing Olivia, a girl Zach was dating, into believing she's a racecar driver. After being interrupted by Bailey and having the situation explained to him, he begrudgingly agrees to help and begins to re-hypnotize London. Despite London assuring him that her mind's too strong to be hypnotized, he puts her back under even quicker than the first time. He then commands London (and unknowingly Olivia as well) to be her true self and not who anyone else wants her to be. While Olivia adopts a new personality that isn't afraid to talk back to her very strict father, London wakes up from her trance with no memory of anything that had happened while she was hypnotized. Interestingly, while earlier in the episode the hypnotized London appeared to be somewhat aware of her past life and personality (claiming that "[she'd] rather go the rodeo than shop on Rodeo [Drive]!"), later on she denies Bailey's claim that she only thinks she's a farmgirl because of hypnosis and seems to believe that she had always been that way.

The Spy Who Shoved Me (Season 2, Episode 1)
The twins get into the secret agent business when a spy loses a microchip that has secret information on it. They hypnotize London into pretending to be a palm-reading fortune teller, in the hopes of discovering the identity of an agent who has a red pinkie finger.

Can You Dig It? (Season 2 episode 18)
When Zack accidentally finds the crown of the ancient Princess Zaria, he takes credit for all the years of research Cody did, making Cody angry. Zaria's spirit possesses Bailey who is now desperate to get her crown back and punishes Zack for taking it. Now, it is up to Cody to save Zack and release the spirit from Bailey.

At the end of the episode Zaria possess London.
