Diana was long gone before Nick, Hank and Theresa arrived to find Kelly's head, so I doubt that she created an illusion for them to find.

My predictions:

Nick, in his grief and rage, kills ALL the royals, except Sean Renard and Diana.

Juliette escapes to wreak havoc yet another day.

Renard sets up his kingdom in Portland, Oregon with his mother, Adalind and Diana by his side, and Nick as his trusty Grimm.

Renard acquires the loyalty of the royal minions, who turn over to him the four keys held by the European Royals. He then gives the keys to Nick to protect. There is now only one more key to find, and Juliette to defeat.
