Titus

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's recent behavior prompts Titus to organize an intervention--to start him drinking again, revealing a wealth of secrets and lies among the participants.

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