DONT READ IF U DONT LIKE SPOILERS COS THIS COULD BE CLASSED AS ONE! (sorry dont know how to do the spoiler box thingy!)
Apparently he's leaving and thats why OB and Mandy and the other sister are returning for a few episodes for his final scenes. I read in a magazine that him and Steph do get married but then disaster strikes so my bets on him dying of a heart attack after the wedding 'cos theyve been bringing up the whole thing with his heart quite a lot havent they.
My friend told me aswell that Tom goes to live with Tony and Jackie, but i dont understand why they would get him, wouldnt Mandy or someone have him?
