At a gala last night, Obadiah confessed to Tony that he was selling arms to Afghanistan. He was also the one who persuaded the board to remove Tony from his position.
They parted on bad terms.
But Tony didn't expect that after making things clear last night, Obadiah would dare take his life today.
The temporary paralysis device next to Tony's ear was something he invented.
It hadn't obtained approval from the Department of Defense, so he stopped developing it.
But the DoD had tested the temporary paralysis device before.
Activating it for five seconds would cause the target to be paralyzed for five minutes. During that time, it would be hard for them to move or talk.
If this went on for a minute, the brain would be damaged, and the patient would become mentally crippled.
If it lasted for more than five minutes, the patient would become a brain-dead vegetable, which was equivalent to dying on the spot.
