Sam and Dean are arguing about whether to go help the little girl that called Bobby's phone. Dean says he wants to go find Frank instead, as it's been two weeks since he gave Frank the numbers Bobby wrote down before dying. Sam goes to check on the girl, while Dean goes to Frank's. Frank says it's only been 4 days, to cut him some slack. Dean screams that he called Frank 4 WEEKS ago. Just a few minutes prior when arguing with same, it was 2 weeks, not 4.
