The owner of the heart
addicted2broadway89 asked for a oneshot of when the locator spell has to be put over something of Emma's it's put over Killian rather than her scarf.
"A locator potion…how does this work exactly?" Elsa asked, examining the small container.
"We just pour it over anything that belonged to Emma. Something…" Charming told her before he looked around the room for such an item. Then Charming spied Killian sitting at the table reading the map. "Something like this." He said before placing the potion on the map in front of Killian. "Pour the potion over where your heart is." Charming instructed him. Killian looked up from the map, puzzled.
"Why?" He asked.
"Well isn't it obvious?" Charming asked, waiting for the penny to drop for Killian. He sighed impatiently when it was clear that Killian just wasn't getting it. "Killian it's been clear for a while now that your heart belongs to Emma now. Just pour the potion above where your heart is in your chest." Charming repeated the command. Hesitantly, Killian picked up the small bottle and poured it onto his hand before rubbing it over the left side of his chest. As soon as he did the area the potion was spread over started to glow. Then, he felt a strange tugging sensation at his heart forcing him out of the door. Elsa, Snow and Charming were all following right behind him as he sprinted out of the door. Now he understood. His heart could now guide them to Emma, well, it was Emma's heart now too.
