The family agree to take him in after he was kicked out of home by his mother, who isn't happy about his desire to help his half-brother Hilton, Cindy Cunningham's sick baby son.
"Seeing as he has no place else to go, he turns to Mercedes for help," he told All About Soap. "It happens because he's agreed to take a bone-marrow test to see if he can help baby Hilton, and his mother's furious about it. She feels betrayed that Alex is interacting with Paul's other family."
Ojan, who made his debut on the Channel 4 on February 13, admitted Alex is under pressure to please everyone.
"That's a big problem and Alex wants to deal with it - he's caught between trying to help his sick sibling, trying to help his mum and trying to help himself. There is this whole barrage of emotions he has to cope with," he continued.
He added: "It'll be an epic struggle as he's pulled in different directions. There are a lot of ups and downs, and that anguish is enough to push anyone to breaking point."
His stay is tipped to cause trouble for Mercedes Browning (Jennifer Metcalfe), because he wants to find out the truth about his father's death.
His dad, Paul, was murdered, following an altercation with Mercedes.
