It's one of the knights, he has been badly injured.

"Princess?" he asks.

"Sir .... um...." you reply

"Rosenfort" He responds

"Sir Rosenfort! what has happen to you?" you ask

"The Vikings have invaded the castle and locked me up down here to rot... I tried to save your brother the prince but I have failed" he says sadly.

You laugh uncontrollably, you clearly hate your brother.

"Princess... the prince is dead" he says

"Oh.... " you say ceasing your disrespectful laughing.
