Diego was a Mormon missionary in Puerto Rico from 1993-95. This is how he learned Spanish.
Diego learned Portuguese while training jiu-jitsu and volunteering as an English teacher in the Favela (shanty town) of Rocinha in Rio de Janeiro, Brazil in 2002.
Diego was married (and divorced) twice. Diego has been quoted as saying "I'm not against the institution of marriage, but apparently I choose poorly".
Diego has never appeared in the series "Vikings", even though people continue to ask him what character he played.
