I wanna see Mike with the party more because honestly that's the biggest crush behavior ever. Like I'm going back through season 2 and when he's with the party and Will isn't there, he only talks about Will. "Will was quiet today" "Is Will ok?" "Where is Will?" "Will's absent and he's not picking up". The entire party loves him and is worried about him but I love seeing normal worry and then Mike who when Will is in even potential *future* danger says nothing but that boy's name. The reason Lucas and Dustin had time for a romance plot and he didn't (he did) was because it didn't matter who she was or what she was doing, or anything for that matter except that he simply did not have time or care for any non-Will side plot. So much so that he became self aware that he was in the non-Will side plot halfway through and remedied that shit IMMEDIATELY.
