Ask him some questions

"Before we start, can I ask you some questions?" You ask the guy. So far he's really different from the various people you met and expected to work for Solvene so you want to use this opportunity to learn more.

"W-well I guess you can Miss. What would you like to know?" He answers with a blush.

"Well first of all, what's up with the Bunny suit? You don't look very comfortable with it so why wear it?"

He flushes crimson and looks down. "It's..... punishment Miss. I don't have a choice in wearing it."

You raise your eyebrow, intrigued and wait for him to develop.

"Well, some time ago, I was a player just like you. I was **** to take part in The Gambler's games and.... I lost. Since then I have to wear this suit and work on this floor. They say that I need to.... earn my freedom back. So they make me work here." He explains.

"Wait, but it means you're not actually on Solvene's side right? I'm here to take her down so why don't you just let me win and advance so that I can get you free." You try to appeal to him. He looks hopeful for a time but then sad again.

"It's impossible Miss. I can't let you win as they'll know. And we'll both get punished for it. I-I-I don't want more troubles I'm sorry."

Maybe you can seduce him to have him help you? If you don't want to do that (either because you don't want to get him in troubles, or don't want to lower yourself to that) you can start the game. You just need to decide if you'll follow the Queen closely or try to get an overview of all cards.
