I'm actually not going to miss Nora. I like the actress but did not like how she was written at all. She's suppose to be a late 20s something but was written to act like a late teen. They should have kept her super young or not done that.
I do think Thawne was fond of Nora. In the same way he was/is of Cisco. Not enough though to not use her for his plans of course.
I thought this season was better than last, but, at least last season had the Nora teases which were at least interesting. I don't feel like this season had much going for it. I think I'd rate them about the same. Awful to meh at best.
I'd really like to know what happen this season. It was all over the place. I don't think it was horrible I just didn't care a lot of the time. I don't think there's been a season of Flash until now where I simply didn't care to watch episodes or even pay that much attention when I did. The only other time this has happen is with season 4 of Arrow.
