It was a scam they were trying to get on more seasons, in front of the camera she didn’t respond to him, but during the tell all she said she loved him as he was walking out. They were playing it up for the cameras, I mean I’m not surprised they didn’t work out, but a lot of it was for show.
In the preview the mom said something like “a mom never forgets” I think she is salty that she cancelled his visa the first time. After that I’m not sure, what else she might be mad about, I honestly don’t think from the preview they talked about her being trans. To me it looks like there are other issues even before that.
