Also, just a thought: I predict we're getting a 2-year timeskip in the next season, and I'm really hoping Katie grows her hair out again.
As for Allurance, I definitely agree it felt rushed. Last season, I did feel that they were growing closer as good friends, but the leap from that to what we have now is a bit...jarring to say the least. I don't really support it, but I'm not gonna deny they do have some development. I just think it was too rushed. But most of all, I don't think the writers properly developed the chemistry between them. Whereas plance's chemistry was being subtly developed from the beginning imo.
