RORY: [starts applying the purple dye] So have you mentioned dyeing your hair to the band yet? LANE: No, but they’ll be cool with it. They’ve all got tattoos. Dave and Zach have musical themes and Brian’s got Snoopy.
RORY: Poor guy.
LANE: Yeah, but he’s a slamming bass player.
Snoopy, Charlie Brown’s dog in the Peanuts comic strip, previously discussed and frequently mentioned. He is a black and white beagle. Comic strip creator Charles M. Schulz based him on his childhood dog Spike, who was a pointer crossed with an unknown hound – presumed to be a beagle, as Spike looked very beagle-like. The name came from Schulz’s mother, who had said if they ever got another dog, she would have named him Snoopy. In the comic strip, Snoopy has an older brother named Spike who lives in the Californian desert. Snoopy has his own star on the Hollywood Walk of Fame, and is a mascot of the NASA space program.
Note how quick Lane is to defend Brian when Rory says something pitying about him. Lane may have only been in the band for a week or so, but she already feels protective of her band mates.
