Alex is a long-time friend of Liz and Maria, though how far back they go is uncertain. Not very much is known about him yet, except that he is the only one out of the groups of friends who does not know the aliens' secret.
Alex is a very warm, funny and uplifting guy. He always has nice things to say, and never thinks the worst of anyone. He is a good friend to the girls, and can always cheer them up.

Little about Alex's personal life is known. Besides being a friend to Liz & Maria, and the occassional flirtations he has with girls, including Isabel, Alex's personal life is still personal.
