Hello. I can actually answer the question as to why he had the last name Hurley. Alex, as he was called by family members, is indeed the biological child of Tommy Tate and Alicia Davis. Alicia was in a long term relationship with another man. During a separation period, Alicia and Tommy had a drunken one night stand, they had been friends for years. Alicia and the other man worked things out and got back together, soon after she found out she was pregnant with Alex. Everyone involved just assumed Alex was this man's child so he was given that man's family name and even started to resemble him a bit we thought. In 2012, the relationship broke down and Alicia and this man went to court to figure out custody of the children, a paternity test was done and it was found out that Alex was the biological son of Tommy Tate and not the man who had been raising him up until that point. It was then decided it was in Alex's best interest to start a relationship with Tommy Tate stepping in as his father figure from that point on. I hope this clears up any name confusion for this case.
