Why is needing Superman's blood sample a mystery? They pretty much made a cure for the virus on the spot while simultaneously fighting off the infected. Not much time to head to your secret cloning bunker you want to keep secret and get whatever genetic samples necessary in order to make a cure.
Wow this is ALOT like Convergance. I thought Secret Wars was just taking into account multiple univereses like Ultimate and 616, but judging by this cover its also covering different time periods like Storm with Mjlonir and Old Thor?
Storm became a Thor full time in a universe where the X-Men stayed in Asgard and Old-Thor exists in an alt universe because that's how time travel works in Marvel.
