The Joker:
Rain doesn't ruin this parade! Every time it rains he takes you outside, you don't mind the rain it's really pretty especially at night. He dances with you in the rain like a cliche 1950's movie but you both love it! You two dry off by cuddling but it doesn't work very well.
Dr Jonathan Crane:
Rain usually means a day inside spent together! You two do puzzles and play games like Sorry until someone gets mad, it's usually you. After playing some bored games, you two settle down and watch something on TV together.
Roman Sionis:
He HATES the rain, he says it causes to much mess. So it's definitely an inside day for you two! When I say "inside" I mean staying in bed together almost all day and basically doing nothing but enjoying each other's company.
Two Face:
He likes to work in the rain. After planning something, he likes to do it in the rain. He says it helps keep thing hidden and it does. You usually stay behind and do some things at home...sleep. But you also worry a lot because he could get caught at any moment.
