King Henry goes mad, and his wife tries to cure him the way only she can (you may've already read this part, I've re-edited it a bit, and the next part is soon coming).

After the events of Reign ep 11, king Henry finds himself wanting to have one last conversation with his wife, only it goes all the wrong ways. Some dark moments and suggestion of violence and sex. You might want to check the youtube video first - it has a slightly different story, but the timing is the same: Poison's Kinder Than the Axe (REIGN AU). Этот фанф доступен на фикбуке.

What if seconds before Catherine's execution king Henry finds out she's pregnant with his child? Dark angsty story, and a rather big one.
