As an epilogue to the Infinity event, Adam Warlock now has all of the stones and it makes him a little power-mad.
Pip and Gamora seek out Strange to come talk some sense into Warlock, which he does, and then in the end Eternity shows up and tells Stephen Strange that he intends to get the stones from Warlock and hold him accountable.
This is basically a prelude to Infinity Watch, the next Stones event.
