Seems as though it will be a single world. Simmons and Daisy said they need to meet up as soon as possible once inside so they can find their team. If they were in different worlds they wouldnt be able to meet up. Thats my understanding of it.

Thanks, seeing Jemma's gravestone at the end of the episode threw me for a loop.

AIDA said she made changes for everybody she brought in... I guess if Jemma officially joined the framework she wouldn´t be dead...

Hope Daisy saves her quick and we don´t get a dragged out no air in the grave plot ;)

Im wondering if its an empty grave. Simmons never made it back from the Hive planet because the team wasnt together to save her so they put an empty grave to remember her but she is still alive on the other planet. Just a thought. Well see where they go with it in April

There's only one virtual world but from what I gather the world changes every time someone new enters in order to adapt to their experience.
