Once she has Jack back in her death grip, she moves quickly. It’s not enough just to have him now, she wants all of him. Especially the part of him that drew all those naked French girls. She can’t bear the thought of him having those other naked girls’ images in his head when he’s looking at her, so naturally she makes him draw her naked, in her suite. Because a poor person drawing her naked isn’t enough of a thrill for Rose, no she needs the adrenaline that comes from knowing Cal will murder Jack in front of her eyes if he walks in on this little art lesson.
Simple Jack sadly thinks Rose actually believes he’s a good artist, so he agrees to draw her. Rose’s thank you gift? Putting the drawing in Cal’s safe, so he’s sure to see it. Because Rose knows that will enrage Cal to the point that he will murder Jack before they reach US soil. And you know Rose, she loves being in the middle of drama. She’s the only woman in cinematic history who builds a murderous love triangle around herself. God forbid she wait to tell Cal when Jack’s safely on land and out of harm’s way.
After Rose plants the seeds for a manly fist fight, she sexes Jack up in someone else’s car. No care or concern for this stranger’s fine car upholostery — just a naive hope that those stains all wash out. Classy Rose.
