Meeting the two women in a bar one night, he got Thelma drunk then lured her out to the parking lot where he tried to seduce her. Harlan got increasingly aggressive as Thelma attempted to resist going so far as to slap her. When she slapped him back Harlan went insane with fury and ferociously assaulted her by hitting her in the face over and over whilst yelling "DON'T YOU EVER FUCKING HIT ME!". He then attempted to violently rape Thelma, cursing her and responding to her begs for him to stop by loudly telling her to shut up. Thelma was saved by Louise who threatened Harlan with a gun. Even though Harlan let Thelma go he regretted doing so right after and openly insulted and cursed both women, proclaiming how he should have gone ahead with the rape. This resulted in Louise shooting him dead. Afterwards a series of unforeseen events beyond anyone's control set a nationwide chase as the law hunted Thelma & Louise who ultimately took their own lives to avoid jail. This makes Harlan the catalyst of the film and the inadvertent killer of Thelma & Louise.
