Mortiss refusing to hang out with his brothers.
Cassius wanting to see all of his demon side as Jacitus only got to see a small glimpse of it in the past. Cassius wants to see how Mortiss can be an huge advantage to destroy Diablo.
Mortiss refuses and says, “You won’t like what you see.” He also says, “I will only develop my shadow manipulation to the fullest extent.” Cassius asked him, “What happens when you reach it, and it doesn’t defeat Diablo.”
“It will”
“What if it doesn’t.”
“It will”
“Mortiss, you need a backup plan, “
“It will!”
Mortiss’s lie: He feels that he is a monster like Diablo and will end up like him and doesn’t deserve love.
Cassius pulls on his collar and says, “There is something your not telling me Mortiss.”
Mortiss pushes him away and says, “There is nothing else to say.”
