Just the way Lucas immediately comes towards Dustin and Mike...
The way both Dustin and Mike rightway bring Lucas into a hug...
The way they both hold him in their arms, to confort him, 'cause, you know, he just got pushed against a wall by a teen way bigger than him and yelled at for simply having been close to Max, but also to keep him away from said teen and to make sure that Billy can't touch him again...
You can tell these kids all love each other so much.
Maturing is accepting that Mike is scared of losing everyone he loves not just El or Will, and that's why he was so upset with Lucas joining the basketball team because he felt it was like losing him, too.
secret relationship byler au where lucas and dustin catch mike kissing will on the cheek, and somehow it doesn't register in their brains that it means that they're dating, but rather it's another special thing only mike and will have. accusing mike of favoritism, they now always demand that he has to kiss both of them on the cheek, too.
the whole party had a crush on Lucas at some point. he doesn’t know this, but it’s a fact.
it probably gets revealed during a hangout in like senior year. they’re talking abt embarrassing crushes and Will ends up admitting that he had a small crush on Lucas in like fifth grade (and if mike is exploding Lucas with his mind? that's neither here nor there). Lucas just pats Will on the shoulder like “it's okay. it can be hard to resist all this”.
but then Dustin chimes in with a “I gotta admit, I definitely had a crush on you too Lucas”. and Lucas is kinda shocked, but expresses a similar sentiment, “like I said, I’m hard to resist”.
then El just nods & says “me too” with a shrug like that doesn't blow Lucas's mind. “wow. I knew I was arguably the most desirable party member but this is kinda shocking guys.”
Max just swats at his arm but agrees with a smile on her face. they all laugh at them and are about to move on when Mike mutters something under his breath. Will busts up laughing from his place next to Mike. and now Max & Dustin HAVE to know what it was. mike ends blushing up to his ears, covering his face while saying, louder this time, “I may have also had... a small... tiny... minuscule… crushonLucastooinlikethirdgrade” and THAT makes Lucas guffaw, “WHEELER! YOU DID NOT!” “Holy shit this is the best thing I’ve ever heard!” “I fucking knew it!”
Dustin is laughing quietly with El while Lucas and Max attempt to breathe through their wheezing. Mike just groans noisily on the floor, rolling over into Wills lap while he laughs at him and pats his head in fake sympathy.
"these are the fruity four" this, "no these are the real fruity four" that. just pick four stranger things characters at random and call them the fruity four. you'll be right
lucas tries getting mike to play basketball because of his height but mike just gets annoyed at him, grabs the ball, and holds it above his head so that lucas can't play anymore.
