Well, this flash pretty much did everything most of us expected to be in the EOA flash.
It will obviously show everyone entering - maybe including the Condesce, through Dirk or Roxy's house. Entering from the future might lead to a different time in the Incipisphere, allowing her to take over before the kids get there.
Showing Aradia and Sollux is also still an option, along with uu waking up.
