If wearing a banana costume turns her into a child, then wearing a slutty outfit turns her into a slut.
The Jill putting Tybalt in his place at the restaurant (and possibly MC too) is the best i've seen so far, she finally got to the point where she showed her true form.... She evolved to this young lady not taking shit and with the fire in her eyes she radiated confidence and beauty.... Sure, she appeals to endearment many times, but cute is cute but the confident beauty aces that.
I really like Jill, but falling back to her usual state still was a bit of a disappointment... Not that it's strange, the anger is gone and we're only 8 weeks into the story of B&R... Reality is she needs more time to evolve, but it is there somewhere...
But Banana Jill still is afraid to show her true self to everybody, she's dressed to impress underneath the banana suit for MC...
She's still worried about telling she is in a relation with MC and immediately goes back to her expectations, the close people are told so next step is introduction to the parents... That's how it's supposed to work right? Same as that "third date"....
