Yes, the lady would have allowed Jaune to bring that guy back home - mainly to focus on the two other miscreants. It s pretty clear that Jaune cannot train on him, but she s actually arguing for a point here and did somewhat listen. Her kind of passion. And yeah, that guy gets objectified so much here. He s really just a tool. Laurels instincts were greed, this guys is Lust, the first guy in costumes was vanity and that angelo guy wrath - if i think about it. But... all of them had lust, too, since Jaune was their target at some point.
Don t worry, this comic is not about the seven deadly sins, though it has some Christian imagery within the story. It s just the religion i am educated with the most If i were to draw on religious symbolism and imagery.
