had when she was a teenager. He lived with his mother, but saw his father Bill (who was married with young twin girls) regularly. He once saved his great-grandmother Isabel Santana's life with a bone marrow transplant. He is a loyal, caring son and friend, sometimes, at his own expense, taking after his mother. He left for college in Tucson in the middle of the fifth season, after graduating one year in advance. He returned to Philadelphia due to a pregnancy scare with a former girlfriend, Olivia, and again for Lu's wedding, and walked her to the altar.
