That's not a cliffhanger. We were having a nice stroll down character development lane and then everything just went black. They really take these chapters and just chop them right in half, don't they?
"Those who are aware of my power, and how it could easily destroy that which offends me know, that my property, Rem and Krum have been taken, and I shall not leave a single stone left unturned to retrieve it.
After a pause, a dirty look, I'd turn and walk out.
Nice and simple. a vieled threat but giving them LOTS of chance to help out... and letting them know WHO was taken (knowing Rem's pretty much loved doesnt hurt either) LOL.
