I'm still convinced El and Mike were broken up all of S5 and just never told Lucas and Dustin when they returned to being friends after S4 because they felt like with Max in the hospital and Dustin probably having had problems with Suzie it would've been a little weird and kinda insensitive to tell them.
But obviously Mike told Will immediately.
Will flirting with Mike makes no sense otherwise. This boy had lost all hope after S4. Mike did some crazy ass gay shit in those 18 months.
The kiss in the void was a goodbye kiss Mike reciprocated because he felt hella guilty and it didn’t actually happen anyway.
This is my canon and you can't change my mind.
