So, if you can tell by my icon, I'm a fan of Doc Holliday in any form of media. I went through a period in my teen years where I watched any Wyatt Earp/OK Corral movie I could find because I was obsessed to see all the Doc portrayals. The only reason I started watching this show was because I was so tickled that Doc was a part of it. So, he is my favorite character for reasons that predate this show. And yes, I ship him and Wynonna.
Having said that, based on the first season, I was 100% certain she would end up with Dolls. They seemed to have this kind of deep connection and they obviously had feelings for each other that they couldn't express because of...IDK, reasons I guess. And Doc was meant to be a temporary fling or the loser of the triangle. It wasn't until the very end of season 1, I thought she and Doc were forming a more emotional bond. Plus, I vaguely remember Emily Andras addressing the triangle by saying something like "everyone chooses a lawman in the end." So, I accepted that Wynonna/Dolls were endgame. Perhaps that was naive of me. It never occurred to me that they wouldn't end up together because Dolls is black. I watched Lost Girl and I saw what happened to Hale. I should have known better. (BTW, I'm still pissed about that. He and Kensi had like three scenes together as an actual couple and then BOOM, he's dead. That relationship was so mishandled).
I'm not sure what happened in season two, but they definitely seemed to change their minds about what they were originally doing with Dolls. He didn't have any authority anymore and aside from the kiss and the spooning, they dropped the Wynonna/Dolls romantic stuff. Maybe it was the pregnancy and making Doc the father just made sense. So, that inevitably gives Wynonna and Doc more of a connection than they previously had. Even now that they've given her up, she's still something they both have and they both love. No one else can get it like they do. But, that's just a guess. I honestly don't know why they seemed to shift away from Wynonna/Dolls to Wynonna/Doc but that's the vibe I got from last season. Dolls barely had anything to do last year. Which is weird because the season started off about him in a lot of ways. Once they got him back, he was just in the background. This didn't really hit me until the season finale last year. He was barely in it. The season finale and the supposed male lead had nothing to do in it. So, if Shamier wanted to leave, maybe he was dissatisfied with how his character had stagnated. They spend a lot of time in the first season hinting at a huge backstory for him and they never really got into it.
In a vacuum, I'm fine with this. Dolls was never a favorite of mine and yeah, I ship the other pairing in the triangle. However, I do acknowledge there is a larger issue here. Even if Shamier wanted to be killed off. They had two episodes this season to do it properly. They could have had a two episode mini-arc all about him and really let him go out in a blaze of glory. It felt like an afterthought. Not a true goodbye to a main character. When I think of great character deaths, this one won't even crack the top 20. I'm not sure what this is meant to accomplish either. To make Wynonna depressed? She's already depressed about Alice. Piling it on like this is just pointless.
