jay and hailey had several chances to get together in my opinion (6x02,6x22 and 7x09/7x10) but that would all have been too early especially since the timing wasn't right and it's better to wait and then it will be done right (8x03) and it it's worth the wait... hopefully you'll find a better balance and that now in season 10 jay's perspective on the relationship will be highlighted and he'll get a good angst drama story, maybe finally in the finale and will be continued in the following season hope so... maybe hailey will get pregnant in the finale and before she can tell jay something bad will happen to him...
You're exactly right! I know that many fans think that Upzek ruined S6, but in my opinion, if we didn't get Upzek, we would have had Upstead by the S6 finale. It would have been rushed and wouldn't have been a slow burn. I know we had to wait almost 4 seasons to get Upstead canon, but I think it was worth the wait. I love canon Upstead scenes and enjoy watching Upstead in love. But I also enjoyed the pre-canon Upstead, when they were just partners and friends. Their conversations and looks in S6 and S7 were just amazing. Upstead's timeline has been perfect. Everything has been excellent, from how they met, their first kiss, to their marriage. I wouldn't change a single thing about them.
I would also like to see Upstead's relationship from Jay's perspective. S8 and most of S9 Upstead have been focused on Hailey's perspective on the relationship. We saw vulnerable Hailey and supportive Jay. Hopefully, in S10, the roles are reversed, and we see vulnerable Jay and supportive Hailey. And if the writers do give us an Upstead pregnancy in S10, I hope they first let Jay and Hailey talk about kids and how they feel about their future.
