^ Yeah, could very well be. After seeing the finale, my suspicions that Zelena may still be alive are greatly diminished.

If that green smoke was in some way Zelena's essence/soul/life force or whatever and it went into the portal then surely it would have tried to change history...but it clearly didn't. So if we go with the principle of easiest explanation, then it was probs just her magic.

Don't get me wrong, I thought the whole "it's her magic granting her final wish" thing to be pretty damn weak. But it would seem to be the writers' genuine intention.
