Hello! I copied from the FAQ:
"Play as Damian and think about his body Saturday evening at the convention. No one else can see this scene art yet because Damian 'works faster' than other characters, and Zobbe already has enough benefits for the time being. A dream with Brock for Zobbe and Jagger will be implemented in the future for more flexibility."
So, you'll have to play as Damian, but once you have it, it will count for all characters.
