Ziva Fey is a witch and she's mad at this guy for not respecting women. She says it's hard to be a woman and curses a guy to swap bodies as punishment. She teases him on how he won't have a dick anymore etc. Really taunting the guy. Laughing about how she'll take his body and leave him in hers. Ziva would then roleplay as the guy in her body and complain about becoming her. He's distraught about losing his dick, having to pee sitting(irrationally focused on this complaining) and just generally unhappy with being her. He then starts to explore his new body and finds that it might not be so bad.
