Two days of near-constant surveillance had not uncovered so much as a secret habit, let alone a whole secret boyfriend. It wasn't nearly as exciting as Anna had expected. She'd used her knowledge of the castle's secret passageways to spy on Elsa when she was in the study, which was most of the time. The only thing she'd found out so far was that Elsa apparently really liked paperwork. That was pretty much all she did. It was super boring.

Kristoff had reluctantly agreed to help, although he made sure Anna knew he wasn't quite comfortable with the whole thing.

Of course, he wasn't quite comfortable with any of Anna's constant rule-breaking, so she wasn't surprised at all. Elsa had forbidden them to be alone together, but Anna figured it was okay as long as they were just talking, right? They weren't doing anything they wouldn't do in front of other people. Still, she didn't bring it up around her sister. Their late-night talks were almost sacred, something to be felt only by them.

It was during one of these talks that things started to collapse. They were talking about the trolls, and how they'd taken Kristoff in, when the first bomb dropped.

"What do you mean, I was there? I've only been to the trolls once, and that was with you!"

Kristoff looked very much like he wanted to hide. "Well, it was a long time ago, but it was definitely you. I don't know what happened, I couldn't hear much." He paused, looking hopeful. "Maybe they just...wanted to chat? Y'know, royal stuff."

Anna shook her head impatiently, her braids flying in a red blur. "No, you said you'd seen them fix ice magic before. I only know one person who can do ice magic." She stood. "I've got to talk to Elsa."

"What, now? She's gotta be sleeping, look how dark it is!"

"Kristoff, apparently I got ice magicked when I was little, and nobody's thought to tell me until just now. Elsa and I need to talk. Right now."

Before he could protest further, Anna took off running. This was important, she thought as she skidded around a corner. Why hadn't anyone said anything? Anna stopped as a new thought occured to her. Maybe Elsa had done the frozen heart thing to her before. Was that bad? If they were little, maybe Elsa hadn't meant to. Maybe it had just...happened. It didn't make sense, though. The only way she was going to find out for sure was to talk to her sister.

Elsa's bedroom was dark and cold. The cold part wasn't abnormal, and neither was the dark part. It was late. She wasn't in there, though. That meant...to the study! The door was cracked open, and a small glimmer of light shone through. Elsa was definitely in there. Anna marched up to the door and pushed it open.

"HEY. Elsa. So Kristoff and I were just talking, and guess what he remembers from a long time ago? Does troll-magic-fixing-ice-magic sound familiar to you?"

Elsa sat up quickly, rubbing her eyes before focusing on her sister. "Anna, what are you talking about? Do you have any idea what time it is?"

Anna briefly felt guilty for waking her up, but then she remembered why she was there, and the burning anger returned. "Nope. Don't change the subject. I know that Mamma and Pappa took us to the trolls when we were little, and I know that they fixed some kind of ice magic in my body."

Elsa's eyes widened. She clearly hadn't been expecting this. "Can we discuss this in the morning? Please?" Her sister's expression didn't change. "Over hot chocolate?"

"...yes. First thing!" With that, Anna spun around and stomped out of the room.
