It wasn't a bad episode, but definitely way overhyped. Flashbacks were good, both actresses delivered, but the big reveal was predictable, so there was no surprise there.
The present day story was too heavy-handed for my taste, especially the lkne of women in the end. It made me roll my eyes, also because I knew it was supposed to make me cry. I think someone upthread mentioned it already - I, too, do not like being told by a show how to feel.
Some of the dialogue was too much "in your face" for me, in both the flashbacks and the present day story. Felt like the writers were desperately trying to educate and lecture the audience and get their message across. Which is fine as such, but it wasn't subtle at all.
I feel like this episode was much more about raising awareness and getting the consent message across than about Jo as a character. I don't really feel like I know her better now and I felt the same way when they finally addressed her abusive husband that came out of nowhere. The fact that she completely shut down after meeting her mother just adds to that. Because if she doesn't talk with anyone we won't know her thoughts and feelings. I hope she does open up to Alex eventually.
The only surprise the episode had to offer is the fact that Jo had an abortion while she was married to Paul. You'd think she would have mentioned that to Alex when they previously talked about what she'd been through with her first husband, but then again we've never actually seen Jo and Alex have a talk about Paul, so I guess not. But Alex and Jo have talked about kids before and apparently it didn't come up then either. The abortion secret per se doesn't bother me so much, but between identity change, abusive husband and and abortion the secrets are piling up. There's so much Alex didn't or doesn't know about Jo and I don't like it. I hope she finally opens up about things to Alex. I get that she didn't want to talk about her mother instantly, but I hope it won't be dragged out for too long.
On a minor note, Alex's time as chief is over now. The fact that it was randomly revealed in his conversation with Jo is almost like a metaphor for this whole story (if you can even call it that). It was random and had no purpose whatsoever. I'm tired of these "alibi" storylines for Alex that are only there so he's occupied with something, but get little screentime and are essentially meaningless for him as a character.
