After making sure the bath was filled and warm enough for them to be nice and comfortable, Chris decided that he should ask if she wanted to bathe together or if she wanted privacy. He decided that he should be a gentleman and not force it. He knows that the system says that the relationship is solid unless he intentionally ends the relationship, He just doesn't want to ruffle her feathers yet.
He left the bathroom, now Infront of Kristen he asks, "Would you like to join me for a bath, or would you prefer to take one by yourself?" He honestly had already fallen completely in love with her, and he didn't just want to have her body, but he genuinely wanted to spend time with her and get to know her. Kristen could see his sincerity and desire and she simply gave a gentle nod of her head as a sign she was willing to join him.
