Because the wager is his to keep at whim. That wager is nothing more than a verbal agreement he could just ignore.
I think she wants to ask a few questions like his pov of what is going on, why he did what he did, etc?
Another thing, the wager is more of a plea as well, because Rose isn't someone chained by contracts or anything, he has freedom and there's no rules attached to his existence.
Erm why isn't she just telling him to gtfo since she won the wager by figuring out his name ;-;
