My controversial tma take is that Martin should've died instead of Tim. Jon and Tim should've been the main duo of season 5 because unlike with jmart it could've actually 1) make for interesting conflict and conversations 2) explore their characters much more deeply especially Jon being a monster without the yaoislop that we got instead what do you think do you see my vision
I think I'm picking up what you're putting down. And now that I'm thinking about it, it would've been interesting if Martin died instead of Sasha. But back to your point.
Unlike Martin, Tim actually had a sort of bond with Jon in the earlier seasons. They respected each other, and I'm pretty sure they were on decent terms. Fast forward to when things started falling apart, Tim and Jon are now conflicted, and that conflict partially stems from the respect they previously held for each other (at least from Tim's side). Add to that Tim's relationship with the supernatural and you have a much more complex and intriguing bond than Jon had with Mr. "avatars are plain evil" Blackwood.
It would've been crazy if Tim in his quest to find and/or avenge his brother ended up becoming the very thing he sought to destroy. Avatar!Tim hating Jon for his feeding, very aware he has to do the same thing... lashing out at Jon because he's an easy target to blame, but the actual person he hates is himself..... every time he'd feed on someone he'd imagine that's how his brother must've felt before he died....
I dont know. The random canon appearance of a fan favourite ship ruined a lot of lives that's for sure
