Miles' moustache
Miles' moustache growing through the facemask cloth the first time is plausible, although highly improbable. Perhaps not plausible but impossible
But removing the mask and then hair by hair penetrating the fibers of the mask multiple times? (i am sure the moustache wouldn't have had been a one off appearance in public). How is that possible?
The movie never addressed this power of Miles
This, coupled with Gwen's hair incident, Peter 1610 and Peter B. Parker having different colored hair, Miles' hair braided in Earth 42, Pavitra Prabhakar showing off his hair - I think I'm onto something about a larger hair related theme
Perhaps they will defeat Spot using some sort of a "bald spot"
