Titus

Titus, Dave and Tommy snoop in Erin's office when Titus suspects she's having an affair.

Titus and Dave suspect their dad is dead: he's been in his room for four straight days--without getting a beer. But they're both too scared to go in and check.

Dave is arrested for grand theft--charges brought by his dad--for taking the VCR when he moved out secretly, per Titus's suggestion.

"All this happiness [with Erin] is freaking me out," says Titus. So he finds a way to sabotage their relationship, as he learned from his father.

Dave and Tommy get a chance to override Titus, whose integrity is questioned when he refuses a customer's request that will mar an otherwise perfect car.

Dave helps, Erin hinders and Tommy panics as Titus jockeys with another driver in a car he customized for Ken's birthday.

Titus is the only one to remain on full alert when his institutionalized mother shows up, officially released and apparently cured.

Ken has a heart attack while driving and blames Titus, who has a picture that proves otherwise.
