....What is going to happen? Is she also a medium but refuses to admit it? What was the scene she was sensing?
For the most part, I imagine it is Catherine's overactive imagination that caused her so much trouble in the original novel. But as far as what's going to happen, Isabella is going to flirt with some other guy and word is going to get back to James and break his heart (tonight or next week or next month, whenever, Isabella is never devoted to any one guy). And Catherine will absolutely stop being friends with her when that happens.
I tried to think of a good way to incorporate Henry explicitly but nothing felt right. So feel free to imagine a coda with him meeting her in the single rider line for one of the rides she loves, or being the uber driver who gets her home safely, or even as the gypsy in drag who hunts her down later to make sure she's still OK. Or not.
