The Egos are seeking the glove, or A glove. Look they're not really sure what exactly they are looking for but they do know that something has got to happen next right?
Will and Mac have disappeared. The Egos now have to find the glove on Canal street and stop the Alejandra's from murdering or whatever. However now there is an Infinity Stone. Actually it's the stone of 1000 exs and it's real.
Pagie and Amber put on the glove and allow the men back into our sketch universe.
