asked: "That's okay. What if before Killian went to NL after Milah died, he went to Lake Nostos to get some water and bring her back to life? Keeping in mind this is pre-Charming, the siren is still there. And at first she turns into Milah, but then she stares into his soul or something and is like, "she's not your true love" and then she turns into Emma. So he gets all angry and freaked out and he's just like "fuck it" and leaves. And that's why he looks at Emma the way he does when they first meet.(?)"
ooohhh, interesting! i could do something with a siren for sure. filing away to come back to later!
