Not that she'd thought about having his children or anything! But definitely a bummer if things worked out down the line.
"I see," Rarity nodded as the picture became clear. At his sigh, she reached out and lightly ran the back of her fingers over his cheek. "You don't have to do anything," she said. "Not that I suggest you let your people fade away, but I wish you would not be unhappy." That, and where was he going to find a girl on the island like him? She didn't know of anyone.
She then grinned cheekily at him, trying to make Art feel better. "You hate saying I can't be yours forever and all of time? That's so darling of you," her eyes sparkled. It was very flattering that he seemed to care for her in such a way. Maybe something could work out, one day. This place was very weird.
