You were Qui-Gon's Padawan before he was took in Obi-Wan. You were close, like father like son. Recently, he was pronounced dead after the Battle with Darth Maul. But he didn't. He only disappeared for 6 years. During those 6 years, you went berserk. As in, depression, refusing to see anyone except Obi-Wan Kenobi. Your friend. Your best friend.
