Mika didn't react even though she clearly sensed Wanda's dismay. She wouldn't ask any more question of her, she knew quite well the fear of being found out. It was one reason why there were certain place she avoided, certain people she tried to stay away from, anyone who might detect her abilities. She wanted to stay safe. She could appreciate Wanda's desire to do the same.
"No, there isn't anything else in the box," Mika replied. "the things that are in the inside are just trinkets as far as I know. Milo only showed me the false bottom so I could have these things. If there are any more hidden compartments, I don't know about them. I seriously doubt it though." Milo had been as concerned about being found out as Mika was so if there had been more, he would have told her so that she could get it. "the box is all yours. I hope someone will buy it who will appreciate it. It's a nice box."
