Terry is back on the cobbles next week as he is planning to open a lap-dancing bar next to the Bistro. He later takes a sudden interest in Tommy (Chris Fountain) when he learns that the mechanic recently inherited a substantial sum of money from his late grandfather.
Tommy has reason to be wary of his dad as Weatherfield's residents try to warn him that Terry can't be trusted.
However, Pivaro revealed: "Terry relies on his wide boy persuasiveness, but he's quite lucky because Tommy is a willing recipient. Like most children who didn't have their parents growing up, Tommy is desperately curious about his heritage.
"So Tommy does make it easy for him! Tina also encourages Tommy, because Terry is new to her and she doesn't know what he's really like."
Asked whether Terry has any paternal feelings for Tommy, the actor replied: "He does, but they manifest themselves in very strange ways, as you'll see! You're never quite sure with Terry, as like all of us in life, he doesn't just have one particular motivation.
"He's governed by many things and issues - by paternalism, by wanting to do right by his son, by wanting to rectify some of his mistakes, and by pecuniary issues as well.
"I think he does care, but he's a survivor and an opportunist. He will take whatever course is necessary to further his interests and his survival. But as he reflects, he'll reassure himself deep down that he really cares about his lad. It just may not be apparent to everybody else, or Tommy himself!"
Coronation Street airs Terry's return scenes on Monday (April 16) on ITV1.
