There’s been speculation on this forum that the series will end with Emma having another child and starting a new chapter in her life. With the uncertainty about contracts and season 7, this new actor could be for a flash-forward to Emma’s “happily ever after”.
I mean like “Sleeping in Light” or “All Good Things” (B5 and ST:TNG). A finale, not a replacement cast.
If season 7 gets the green light, then we can have flashforwards instead of flashbacks.
