In my perfect worldstate, Varric and Hawke adopted Rook, merely because it would super funny to see how Varric became more responsible and mature due to his circumstances, while Hawke remained the same troublefinder (yeah, finder, as in they're always finding trouble by accident), and dragged Rook to the same fate. So now Varric has to watch over his spouse and child while dealing with every kind of shenanigans, from politics to crazy cultits, from protecting the world to bar fights. Even in his Inquisition times, his life was less tumultuous, but he's not complaining 'cause he's with his favorite troublefinders.
