Yeah, we know: When Logan first arrived in Season 5, he was an ass. But throughout the last three seasons of "Gilmore Girls‘" run — as well as its "Year in the Life" revival — Matt Czuchry’s endlessly charismatic character not only matured quite a bit himself, but played a crucial role in Rory’s character development.
