Mike's behavior in 4x02 is unnecessary, it is dislikable, and most importantly, it is distracting.
And THAT is why he's queer.
It is. distracting. Where they could have had Will jealous in a way that could be nothing but romantic because of how it contrasts Mike's totally normal behavior to make us question Will (i.e. Mike tries to hug him because it's always been normal in their relationship for him to be physically affectionate but Will is suddenly weird about it for no reason, warranting a reaction), instead they created an overly-empathizable situation in which any of us would have reacted the way Will did to a friend doing what Mike did.
Now we have no questions. Now we are not questioning Will's behavior as his sexuality because there is nothing about it that is out of the ordinary. The situation warrants sadness. Mike's behavior warrants reaction. The way to establish a question in the audience's mind to set up for its impending answer for them to be invested in is to make them act in a way you WOULDN'T. Have Will be "rolling his eyes [and] moping" but actually uncalled for. Have the fight, Mike initiates it anyways, but have us on his side, seeking answers with him. And maybe he goes too far in a similar but not as out of character way and that shift to the apology prompts him to forget to question Will's behavior for the rest of the season to put the plotline off.
But that's not what happened. We. were. distracted. After the comment about Will acting "weird" and the rejection of the girl in his class, I'm sure some people were starting to put two and two together about Mike and even anticipating, curious what "weird" behavior he would have with Mike....He did not get a single instance of this. Because Mike did not get a single instance with it absence. In not having Mike act normal to contrast Will acting "queer", if you get my double entendre, there is complete deniability in everything Will does to the extent of possibly erasing those questions entirely from some viewers' minds. If my friend ignored me for their partner all day, I would feel hurt and rejected. I would get grumpy. If they became defensive about something I was never accusing them of, which also implied things about me that I had been bullied about, I would be hurt. Normal. On all accounts.
This episode and Will's jealousy are (supposedly) not supposed to think he's MORE normal. But he is left being straightman (forgive me) to Mike's abnormalities.
It's distracting. Mike is COMPLETELY distracting us from every scene where Will's behavior otherwise indicates his queerness. Because it DOES. He IS romantically jealous over Mike. But they gave us an alternate reason for his behavior in making Mike ACTUALLY ignore him. Now, we have no idea if he would behave the same had he not. There are still signs and because queerness is still one OF the explanations for Will's behavior, I can't exactly argue that it erases Will's plot here to serve towards his queerness entirely...but I'm going to! It totally does, for some viewers at least! Mike's behavior makes you unable to confirm for yourself, or even confidently question, that Will's behavior is "weird" as his sister described. Worst case scenario, you now think that she's WRONG because he's acting normal and she doesn't have the best history with social cues - and she's acting pretty weird herself right now.
All this to say, the writers sat down in a room and said: "It is important enough to have Mike behave this way that we are willing to sacrifice valuable screentime to establish Will's queerness, a very important and focal plotline of this season."
That is an active choice to make. The only reason to write a pointless, contrived conflict that is desperate enough to be out of character and end the same way things were before it, on normal terms, is if you are completely barren of ideas. NOT if you already have an arguably more important plotline to put in the same spot that you are sacrificing to it.
That is a difficult choice to make. They had to say "Will's queerness, something we have held dear to us, are very excited about, and have given great weight since the conceptualization of this show, is not as vital to the story here as Mike being a dick for one day then immediately apologizing and stopping forever."
Now, what an odd thing to say...
