Mamya,
Yeah,the crosswordsolverists on here aren't what they were are they.
Do you think it would be OK for either the strict teacher/naughty pupil or viking/saxon peasant scenario. Of course, I would let you decide which and indeed who plays who.
p.s. don't tell The Joker he'll only want to get involved someway- I expect you have read about some of his carryings on.
