Doug doesn’t like to talk about his past. None of the other detectives know what he was like before he came to SEVEN-O, either. But he does show an obsession with investigating a certain man…
If you promise to leave me alone, 
I'll tell you everything I know.
،إن وعدت أن تتركني وشأني
.فسأخبرك بكلّ ما أعرف
Ich erzähl dir alles, wenn du mich
in Zukunft in Ruhe lässt!
Te diré todo lo que sé
si prometes dejarme en paz.
Te diré todo lo que sé
si prometes dejarme en paz.
Se prometti di lasciarmi in pace,
ti dirò tutto ciò che so.
Se prometer me deixar,
eu conto tudo o que sei!
Обещаю рассказать всё,
что знаю, если оставишь меня в покое.
