[She takes her time removing those bandages over her tattoo, and getting lotion on as best as she can. He can help her get it on really good later. For now, she's in a hurry to get over to that trunk.]

I was wondering what's in it. Why would he keep it locked like that?

[She doubts it's weapons or anything. Most people wouldn't leave those in a secondary bedroom. It's probably not money or jewels, because he doesn't have any need for them. So she's insanely curious about what it could be.]

I've got my hairpins, if you think you could get the lock open. But he has to have the key around here somewhere. Let's try looking around.

[There's absolutely no issue in her mind with stealing the key and looking inside. They're just curious, it's not like they're going to take what's inside. It's all innocent, good fun. She grabs his hand and pulls him off the trunk, and laughs as they make their way out of the room to see if they can find a key.]
