[In Chuck's Cafe] What if he followed me out, though? Started after me again? I'd be right back where I started; even if I got a lead, he'd overtake me soon enough. He's got some, some, some souped up diesel; my car's just not that powerful, I just can't break eighty and ninety miles an hour. As soon as I stop concentrating, I'd go back to sixty or seventy like I always do; it's a habit, I can't help it, he's just... [pauses] take it easy...just, take it easy.
