What Carlos does not know is that his wife contributed to his mother's death too. Juanita was actually running from Gaby and John after she discovered their affair and took a picture of them having sex. That's when she got hit by Andrew's car in the street. Carlos needs to look more into what really happened that night, since he wants to hold onto the past that much. Technically it is also his fault, since he asked his mom to come keep an eye on his wife. lol... He should stop blaming Bree; he is not a saint himself!!!
