If that were how it worked, then surely "but I thought you liked it" would be a legal defense?

I did try to write Stephen's terror at the end there so it felt like a suitable comeuppance -- so that it's believable for Jon to consider the score settled, even though not everyone in that situation would necessarily feel the same way.

My next Potterverse J/"S" fic will be less of a moral quandary, never fear ^_^;
