- "Don't make me throw you outta here, Thad. You don't need to make a scene."
"Oh, brother. The scene... has only just begun."
- ―Sid Sivana and Thaddeus Sivana[src]
Thaddeus interrupts the board meeting of his father. After a brief exchange with his brother Sid, he throws him out the window to his death. After this, Thaddeus unleashed the Sins, letting them slaughter the other board members, leaving only his father alive. Begging for his life and offering Thaddeus the company, Thaddeus taunts his father that his sin is Greed, and leaves the board room, allowing Greed to finish his father off.
