Good point. Rumple said she followed Emma which was odd. The only way I can picture this is if Zelena's magic/life force simply opened the portal, as we'd previously gathered pre-417, and for it to work someone still actually needed to go through it or... I don't know man. Zelenarian was created during 408 writing time man. She just was.
