Maria didn't trust anyone. She told me as much after you... Never trust anyone. Trust gets you killed. She wanted me to use it as a lesson, take it to heart. Didn't really work. As you'd probably already guessed, considering.

I should tell you about the time I injected Clint with mind altering nanoprobes so Nick could shoot him and not have him remember it.
