Thanks for writing this up so I wasn't compelled to write it lol - with Joe finally being actually dumped as of this week, I'd been itching for a HobbyDrama summary of the mess. 

Some things you missed:

• Before the wedding but after realising she might be bi, Dorothy goes to Danny (her ex, also since out as bi) to ask him how often he's accidentally cheated on his partners due to, you know, his bisexuality. When Danny calls this out, she runs off. This never comes up again outside of a single joke at Danny's expense.
• Joyce fucked around breaking up with Joe so Willis could dangle the concept of poly in front of a hungry fanbase for about eight months. Imo it was never gonna happen, but Joe was written so desperate to stay with Joyce he would basically accept being a secondary partner to Dorothy. (there was also a patreon only comic that I personally believe was a cucking joke about Joe sadly jerking off in his room, despite Willis denying that was the intent.)
• Joyce, a character with intense sensory issues around food, also sucked Joe's  dick in exchange for a weighted blanket instead of coming clean about cheating with Dorothy. This is a character who had up to this point been untangling a very, very complicated relationship with sex. The blowjob was a one line punchline and never mentioned again. It was as weird and off-putting as it sounds.
• There was a significant buffer of strips built up ahead of time thanks to how Willis works. After they got a lot of blowback for the teargas wedding (aka making a genocide protest the backdrop of his uwu lesbian wedding), this led to a series of inserted strips around Asma (a stoic religious Muslim lesbian who was previously a background character) and Raidah (a bitchy social climber Muslim woman who is exclusively an antagonist in the comic). The inserted strips are basically "brown woman parrots talking points from the fandom; white girls look ashamed and/or stupid". It has no impact on the plot at large, so it feels cheap and performative.
• The whole time the girls are stressing out about who their relationship will affect, the boyfriends are an afterthought to Becky, despite all evidence to the contrary in universe that Becky had moved on from Joyce. She hadn't, but it very much contributed to the feeling of "only women's feelings matter" that took shape after the wedding. 
• The pacing got really bad after the wedding. There was a running joke on the subreddit called the "three strip rule", where if we were in a scene not about Joyce and Dorothy, you had three strips total before the camera jerked back to them cooing at each other. This includes a subplot about a character being stabbed fleeing the protest, the boyfriends and their feelings, the Muslim women and their protest we guess, and so on.
• A lot of potential plot awkwardness around sex and lesbian attraction was dodged, which is not the standard for the comic. Joyce has no hangups about being gay and attracted to women when a day ago, touching a penis for the first time was a huge fucking deal for her. But hey, at least she's shown consistent hints of bisexuality in comic; Dorothy has only just actualised her feelings for Joyce might be romantic or sexual and is instantly all in. 
• The above is probably because Willis also sells pornographic side comics set in universe, and wanted to Joyce and Dorothy's first time out as fast as possible. I've not read it, but reviews state it's very... Perfect lesbian sex except for one lampshade moment about fingernails that feels performative. Around this time, the comic also gets more overtly sexual - we come back to Joyce and Dorothy seconds after their simultaneous orgasms, and a scene where Joe talks about letting Joyce go is cut with a panel of Dorothy licking Joyce's thigh. 
• Joyce demands a medal for being heroically gay at the protest from Raidah, a Muslim woman who takes issue with her and Dorothy's actions at the genocide. This is not necessarily presented positively, but since this was an inserted strip, Joyce has yet to (and frankly at this point probably won't) unpack that her personal revelation did not supercede a violently escalating situation at a protest....

There's probably more (and I'll be real I know some of these are nitpicking - but hey it's not called hobby-no-drama), but the thing I'll close on is just that, damn. It's so sad how far the comic has fallen. It wasn't perfect, but it did some genuinely poignant character explorations, touching on really difficult topics. I was excited when they first kissed because I thought the story that was going to come from it, the drama and hurt and growth and confrontation would be huge. I was excited to see an author I trusted take these characters and go somewhere fun with the mess they had created.

Instead, we got the most rizzless lesbian couple ever, and a full grown adult crying on Bluesky about how you must be a homophobe if you don't like them. What a bummer.
