Vincent thinks back to his time in Afghanistan this week.

When he receives the adrenaline, Vincent remembers.

Catherine's mother was an imperative part of the experiment with Vincent.

Catherine visits her dad to find out what she can about her mother.

J.T. helps Cat find her mothers notes for a possible serum to counteract Vincent's side effects.

Mrs. Chandler tried to speak up for the test subjects and Vincent came to her aid in Afghanistan.

Vincent refuses to wait for the serum to be tested, and injects himself.
