I actually think that Will going to Mike and banging loudly on his door was a perfect callback to their breakup, when he stared at his door and quietly walked away.
will isnβt chasing after him. mike fucked up and he needed to be the one to reach out first, but itβs just as important for will to as well bc he has also fucked up. theyβre not going to make any progress if they dont talk and show each other theyβre willing to work things out π€·π»ββοΈ
