When Varric finishes his story, Cassandra eventually realises that it was Hawke who was the Archedemon, Varric is asked to testify against Hawke. He refuses, and limps his way out the door, sobbing and crying.
Dissapointed Cassandra drinks her coffee in front of the message board in the office - suddenly, she freezes, shocked, and drops her coffee mug (it breaks). When looking at the message board, Cassandra realised that Varric's story, from the beginning to the end, was completely made-up, mastermind, when Varric first gazed at the board. Each name from the story, Such as Bethany, Carver and others were actually a memo or a page appearing on the board. The whole story was made up by Varric.
Cassandra looks down to the broken cup, and it reads -"Hawke has a giant beard" thats the name of the cup's manufacturer
Cassandra rushes outside to capture Varric, as an eyewitness sketch of the archdemon arrives at the station. The sketch perfectly resembles...Varric. Outside, Varric limps his way through the crowded street, when suddenly his foot straightens and his 3 "Paralyzed" fingers come to life. He ignites a cigarette and enters the limouzine (wierd thing is that cars don't even exist in Dragon Age) where his lawyer, "Flemeth", picks him up.
As Varrics car disappears on the Horizon, Cassandra stands in the street, frantically searches for Varric.
"The Greates trick the Archdemon ever pulled was convincing the world he didn't exist." says Varrics Voice over as the screen turns black - "And like that...He's Gone."
This twist has never been done before, right?......nevermind....
