In a mild cliffhanger ending to the episode, Rory’s father Christopher Hayden (David Sutcliffe), who has been living in California for some time, unexpectedly arrives in Stars Hollow.
We at once understand why Lorelai loved him as a teenager, but rejected him as a husband and co-parent to their daughter. Christopher is good-looking, charismatic, and rides a cool motorcycle, but is clearly unreliable and immature – it’s hard not to cringe when he yells at Lorelai to take her top off in front of their teenaged daughter.
It’s also obvious that Rory adores her father. The way she eagerly runs to him for a hug demonstrates the longing she must have felt to have a father in her life – even an unsatisfactory one like Christopher. While Lorelai knows what Christopher is like, Rory still has stars in her eyes over him: just as Lorelai must have had seventeen years ago.
(Christopher looks astoundingly clean and refreshed for someone who has just ridden his motorcycle for 3000 miles; the bike is very clean as well).
