Chelsea exposes Jimmy on a podcast & it explains what Jess said on Nick’s podcast
She says the night of her biggest fight with Jimmy when she got angry with him for going out was not shown in context on the show. The previous night, she says Jimmy asked if she would be okay with him spending the night at his place instead of the apartment the show gave them. She agreed to it and got a FaceTime call from him in bed saying he was tired and was gonna go to sleep early.
A few minutes later, Jimmy butt-dialled her and she could hear him surrounded by friends, including the girl he slept with, talking about what bar they should go to next.
This matches up with Jess on that Nick guy’s podcast earlier this month when she said that Jimmy goes out a lot, way more than is shown in the final edit, and that he did stuff behind the scenes/lied about stuff which made Chelsea worry about him messing around with that friend of his.
