It's implied that Leticia's (the random French girl that let Jannu share her body) personality rubs off on Jannu. I personally don't believe that because Leticia doesn't do much. Her relationship with Jannu isn't like Yugi and Atem's, in which the latter pair speak to each other regularly. Not only that, there's no subtle visual differences that serve as a cue to tell which one of the two are in control (not counting boob size). For example, why not give Leticia soft eyes and neatly combed hair and give
Jannu messy bangs and hardened eyes? But I digress. To answer your second question: it's out of character.
