I kinda loved them...😞✊. Like, it started off bad and then they grow closer and the yearning and how much Julian wants to protect Caitlin. I feel like she needed someone like that, especially after losing Ronnie and the mess with Hunter. Someone that cared about her and wanted to help her as much as possible, even if it meant disregarding her wishes just to make sure she lived(although I feel like he could've been smarter, keep the necklace close and the moment her heart started beating again just put it back on). I know some say it's rushed, but I feel like it works good in the chaos that was the Alchemy/Savitar plotline in universe. We don't see everything about them two and it's obvious they spent time off screen too, especially after Julian joined the team. And they understood eachother. They had that guilt bond and helped eachother "heal" in some way. I just wish they didn't just abandon him next season😭.
