"Where are we going?" Greg asked.
"To see my friends"
"Why?"
"Because he's ill" John pointed at Sherlock, who shuddered. Greg patted his arm.
"It's going to be ok"
"R-right" Sherlock muttered.
"Ooh look! You have a pretty white streak in your hair!" Greg pointed excitedly, and Sherlock reached up to touch his hair.
"No, Greg, I've had that for ages"
"He's right, your highness" John said gently, and Sherlock shuddered again. "We have to hurry"
"Hey guys! Look, we really need your help" John called, striding over to a pile of rocks.
"Wait what? What is he doing?" Greg asked, and Sherlock shook his head.
"I don't know" he muttered, pulling his scarf tighter against his neck.
"I'll distract him while you run" Greg whispered, before going and patting the top of one of the rocks. "Hi Mary's family!" he glanced back at Sherlock, who looked amused. "Why aren't you running? I insist that you run"
Suddenly, the rocks shifted, and Greg gasped.
"Trolls?" Sherlock asked, confused, as the trolls all hugged John, pulling his coat and shaking his hand.
"Hey, hey, nice to see you too! But we've got a real problem"
"Are you hurt?"
"No, no I'm fine. It's actually Prince Sherlock that needs you" John gestured to Sherlock, and the trolls turned to rush to him, touching his coat, examining his face.
"He's very pretty" one of them remarked whilst Sherlock stood still, his jaw clenched.
"He's cold, John, what did you do to him?"
"Nothing! His brother, the king, he... sort of fired ice at his heart" John mumbled as the leader of the trolls, the wisest and most ancient, came forward as Sherlock's knees buckled. John caught him, noticing with a start that the white streak in his hair now covered more of his head than before. The leader touched his forehead.
"His heart has been frozen"
"I have been reliably informed I don't have one" Sherlock muttered, remembering what he had been told several times and still managing to be his usual snappy self despite his weakened state.
"But we both know that's not quite true" Greg giggled, taking Sherlock's hand.
"There is only one thing to thaw a frozen heart"
"Which is?" John asked, desperation in his voice.
"Only an act of true love can thaw a frozen heart, or to ice forever he shall freeze. Kiss him"
"What? No! We're... we're not... not a couple!" John spluttered.
"Are you sure?"
"Of course I'm sure! He's engaged, he's got a fiancé, he's going to get married, he-" John broke off and looked at Sherlock, who had curled up on the floor. "Molly"
"What?"
"Molly. Your fiancé. An act of true love" John said, and Sherlock blinked.
"Molly... yes..." he mumbled, and John helped him up as his hair continued to turn white.
"Come on, we've got to get you back right away. A true love's kiss from Molly should help"
"Let's go and kiss Molly!" Greg shouted as Mary carried them back to Arendelle. "Who is this Molly?"
