Shortly following the London UFO crash in 2006, Rachel posted on the website Doctor Who? to ask if any of the aliens were single as she broke up with her boyfriend Robbie last week and she felt it would be a good opportunity to get back at him, imagining his face if he saw her fly off with an alien. She suggested that going to the local cinema in a spaceship would be a bit more impressive than being driven around in Robbie's dad's Mazda. (PROSE: Alien landing confirmed)
