Tbh I think the “Will Voice™️” is one of the biggest pieces of byler evidence
When I was rewatching season 1, I noticed that Mike did use a gentler voice with El… for like an episode. When he thought that Will was dead however, that act immediately dropped and it barely ever came up again.
(While he’s flipping through Will’s paintings may I add)
He was gentle with her a few other times yeah, but when season 2 rolls around he kinda doesn’t use that same tone again. He seems more anxious and hurried than gentle when he tries calling her on the walkie-talkie. And then in season 3-4 he just isn’t gentle at all lmao, he even gaslights her in s4.
Ah yes the speech of true love…. “You’re acting crazy!”
Compare this with Will, there are like… 2 moments when he doesn’t use a gentle tone of voice with him, and in both he sees Will’s face and immediately becomes gentler. In season 2 he tells Dustin and Keith that “I’m not prostituting my sister!”, but he also tells Will that “If we’re both going crazy then at least we’ll go crazy together right?”
In season 3 when El “dumps his ass” he makes a face halfway between disgust and annoyance. When Will gets mad at him, right after he snaps and says “it’s not my fault you don’t like girls!” His face IMMEDIATELY softens and he tells Will that it was a great campaign. (And afterwards he even biked over to his house in POURING RAIN just to apologize)
In season 4, he gets agitated when Lucas tries to get Hellfire postponed. He also swears that he says “I love you” to El even though he never does, and he eventually ends up calling her “crazy”. Compare this with Will, when after rink-o-mania and they had their fight there, a few days later he apologizes and recognizes he was in the wrong, while asking to work together as a team again.
That scene was also just… a whole analysis on its own. My point is, if he loves El so much and doesn’t like Will, why is Will the only person he’s CONSISTENTLY gentle with throughout the whole show??
