It's apparently going to be a prequel. About Lily. In the 80's. Which...I guess is pre-Rufus by a lot since they've made a big to-do about Lily and Rufus being together in the 90's/Lincoln Hawk being a one hit wonder 90's alternative band, etc. (which, by the way, I always picture as Gin Blossoms-y). The whole Lily/Rufus timeline is a little sketchy anyway, so maybe they'll just say fuck it and find some adorable Matthew Settle clone to play young Rufus.
*I know I'd normally post a picture of Kelly Rutherford for a story about Lily, but damn, Matthew Settle is hot.
