The actor revealed that Lucas will receive a huge shock in 2012 which could ultimately have a positive impact on his life.
Major told Channel 5: "Lucas is about to be hit with the biggest surprise which is going to rock his world initially, but could be the best thing that has ever happened to him."
Meanwhile, asked to name his favourite storylines from 2011, he replied: "Lucas coping with the death of his father was really interesting to play and the crazy girlfriend Michelle stuff, which was really fun."
Last month, Major told Digital Spy that Lucas's edgier side could be revisited in 2012.
"There is a lot planned for next year where you see the other side of Lucas and it's not pretty," he said at the time.
