Alas, he cannot stay the night, work to be done at home and his daughter would probably raise a rescue party if he were gone too long, but he does apologize again for his caution no matter how prudent it might have been. He personally thanks Mary Ellen for the fine coco, which causes her to blush, and soon he is on his way out with a promise that those seeds would come soon.
