Will Jane ever learn to respect other people's feelings and their boundaries? Will she ever stop doing things out of spite because something doesn't go her way? I guess, the writers wants us to watch the last season and find out!
The entire situation with Mateo being tested is a pure obnoxious Jane, Like, girl, Rafael freaked out, give him some time to adjust to the idea and calm down. Instead she willingly worsens the issue by making an unilateral decision and expect Rafael just to fall in line.
Rafael's also acting out because he just found out Luisa is allegedly works with Rose and is lying to him. Plus his son is having some issues, and his co-parent doesn't try and talk to him about that but just starts a fight to hide her feelings. I'm glad he and Jane came to an agreement and made up, and that Rafael was serious about the medical issues custody.
BTW, it's interesting how they show Petra helping Rafael the way Jane was supposed to support him in the moment. It got way better results.
The entire episode was weird and hectic, probably by design, though. Yes, the Narrator is Mateo, I knew that already, show, stop!
