Maybe I'm just pessimistic... I really don't want anything to happen to Regina though. You might be on to something.

It is quite possible that Zelena, is collecting blood samples, from all her living relatives. She is Regina's half-sister, and possibily also Snow White's. She might have tricked Hook into finding Emma, and bringing her back to Storybrooke. Obviously, Emma would never leave Henry behind, even without his memories. Then, there is the unborn Charming baby, who Zelena has taken a special interest in.
