He very nearly caught Ian and Mickey the first time they slept together, but despite finding them naked together, simply told them to put some clothes on and thought nothing of it, probably assuming they were on drugs. It is later discovered, due to his constant drinking and blackouts when he would raped his daughter Mandy.
Terry had hunted Ian down because he thought he was the father, until Ian and Lip tried to plant an illegal gun in his possession, only the plan back-fired when Terry came home. Terry made a reach for the gun as Ian and Lip began to run. Lip managed to jump out of a window. Ian however, got cornered by Terry in the kitchen only to have Mandy interfere by holding a shot gun to him. As it turned out the father was in fact Terry. The revelation of his impregnating his own daughter disgusted both Ian and Lip.
In Season 3 it is revealed he has another child other than Mandy, Molly, which is revealed when she tries to call him saying her mother has died. Molly is the half sibling of his other children.
Terry finds out about Mickey’s sexual orientation and takes matters into his owns hands to “straighten” Mickey out. He walks in on Ian and Mickey having intercourse and attacks Ian, shouting “Mandy wasn’t enough?”. Mickey tries to interfere and manages to wrestle Terry away from Ian, but ends up receiving the brunt of Terry’s beatings himself.
As Ian tries to run, Terry points a gun at Ian and tells him to sit back on the couch. Mickey, barely conscious now, tries kicking Terry off, but Terry hits him with the base of his gun and puts Mickey out. He then calls a Russian girl over to have “corrective” sex with Mickey.
When the girl arrives, Terry tells Mickey she is here to “fuck the faggot out” of him. Terry forces Mickey to have sex with Svetlana and makes Ian watch. Mickey is seen to be in pain and looks at Ian, but Ian can’t return his gaze, emotionally in pain himself. After a short while, Mickey rolls on top of the girl and away from Ian, so that his back is to Ian and he wouldn’t see him. He acts like he is suddenly enjoying the sex to get it over with as soon as possible, while Ian watches in dismay.
In Season 4, while the prostitutes are stuck at the Milkovich home for a time duration, Svetlana and the others yell at Mickey while Svetlana adds that he “also has small dick”.
Terry blames Mickey as well for trying to “liberate” the prostitutes and adds “You do have a small dick” and “This is my house”. Terry says it is indeed his Mickey’s fault because he actually believed the prostitutes deserved more (money) and thought he could “liberate” them, and says from his father’s (Terry’s) experience, she (Svetlana) is not worth anything more.
Later in season 4, Terry is seen being hauled from his house by several policemen while yelling profanities at them. He had apparently failed another urine test, thus violating his probation. He is sent back to prison.Terry is released to go to the christening of Mickey’s son, and arrives later at the Alibi.
Mickey and Ian fight about their relationship and, before Ian leaves, Mickey gather’s everyone’s attention to announce that he is gay. Moments later, a furious Terry lunges for Mickey and instigates a bar brawl. Mickey and Terry are apprehended by the police while Terry continues to shout homophobic slurs, and continues his aggression as Mickey provokes him. Terry is taken away by the police for breaking probation just hours after his release, while Mickey is released by a gay cop.
