Oh no

Say, have you discovered anything from your tailing.

To be honest nothing much, at least I made sure she didn't go to the north mountain-wait.

Should I tell her that disguise makes her stick out like a sore thumb?

nah.

Thanks for coming to see me. See ya tommorow!

It's an emergency, I gotta go! Don't tell anyone you saw me.

eh? oh sure.

that's right, I almost forgot-

Someone has to tell her

uh, she's going away again, where's she going now?

Wasn't talking to that maid just then? she should be going upstairs, since that maid just came down from the stairs.

...wait. my room?

There's the library my room and Elsa's room upstair. If she's delivering tea to Elsa's room or the library, there is no need for her to tell Elsa. So that means it has to be my room, which means Elsa is going to my room. Ah I see.
