He (Ali) could marry Charlie, and they move into the bunga, beekeeping. Charlie can mansplain the world to gormless Ali.
Lydia moves into the TOR. Josie and her exfoliating each other with globy and practice mud wrestling in a tub full of St. Tropez.
Edit: The more I think about it, Charlie and Ali are a match made in heaven. I don't care if they are straight, bi, or gay. IT HAS TO HAPPEN!
They could cook with each other, play board games. Care for the "garden". Have barbecues. A bunch of cats and dogs. Care for the bees. Go on travel. Have friends over. Redecorate the bunga.
Then in the evenings, lil Ali sits on the floor and Charlie read to him a few pages out of the British Encyclopedia.
