HOW CAN I GET ATE TO REVEAL WHAT SHE KNOWS?

Have you asked her about Sven?

She knows something but she won't share until you figure it out too. Helpful.

What did she say about something frozen?

Have a look around the castle for something that fits that description.

Look at the ice sculpture in the dining room.

So melty. But you can't get a good look with Maggie standing there.

Maybe if you talk she'll get bored and leave?

Showing her the amulet you took from Busby's pocket will spook her enough to get her out of the way.

Notice anything strange about the ice sculpture now?

The N looks like it hasn't melted at all. Tap it to examine and take a memory of it.

Go talk to Ate about it.
