Here what we know,
Mikey is claiming both he and Taz are VT who somehow have the ability to know eachother's role/affilitation, yet are not linked by death
He is trying to no be investigate
Claims that mafia won't attack him or taz since why would they go after "confirmed" VT

So he is setting it up to not be investigated, yet have a viable excuse why neither of them died at night, and one of the two will likely draw the doctors protection so they can always fall back on that.

Seems suspicious as fuck, especially this early in the game and the first thing he fucking says. In no way does this help us on the first day, it just confuses the fuck out of everyone and draw tons of attention to you. So either you are an idiot who played his role the worst way possible, or you are mafia and did just what you wanted to, cause confusion.
