Can one conceivably, for fanfic storytelling purposes, say that the MCU and AoS universes are one and the same? I mean we've got crossover characters and overarching plotlines that connect them so, to me, AoS slots far more nicely into the MCU than the X-Men films do (despite having two characters in common). So for me, I'm just going to assume the two universes in question are the same until i am proven otherwise.
