He isn't sure how he would feel about meeting Papillon again. Would it be different now that he wasn't forced to entertain her? What would she do if she say him? Would she have him captured and sent back to his step parents?
On the other hand, the only lead they have on the gem that Ruby had is a warehouse that some of Papillon's guards were at a few weeks earlier.
Should Emerald go and try to meet with Papillon? Or maybe they should exhaust all the other lead they have first.
