I don't really plot a whole lot, so any chance that there will be more less-violent ambitions like the ones we had in EU Rome--get character X a title, get this minor_title, go to war with X (for holy wars perhaps), excommunicate X, become a poet, have a grandchild? I guess I get tired of all the cloak and dagger--depending on character traits, it would be better to have everyone believe that your rival is a heretic than to have him die in his sleep.
Finally, how about some childhood ambitions, Johan? There's not much to do when you have to wait for your regency to be up, and your fosterlings should get ambitions, too, that you can approve of or not.
