Alessandro Roux

Job Titles:

Just ask Minerva, who has had Carlito save her when her car broke down. She even got him to check her new car before she bought it, because he is the real deal when it comes to cars. Along with Tetun, his native language, he is fluent in Bahasa and can hold a basic conversation in English. Especially if it is about cars.
