O'Neil (Day 2)

O'Neil was a CTU agent active during Day 2.

After Nina Myers was brought into CTU in connection with the bomb, she was granted a pardon in exchange for providing information about the terrorists. George Mason planned to use O'Neil as the handler, but Jack Bauer told Mason to forget about him. By blackmailing George with the knowledge of his radiation sickness, Jack was placed in O'Neil's position of handler for Myers.
