Lol. I don't know, I think a cake is reasonably good evidence. Not quite as good as seeing Kinnetik printed 5000 times on a door, but not too bad. ;)
IMDb also lists her as 'Linz' but I would never have taken their word for it. They do frequently get character names wrong in many of the shows and films I've looked up there. In fact they still have at least one major QaF character name wrong, and have for years despite multiple people submitting corrections: they list Brian's boss' name as 'Pancho Ryder' even though we know his name was 'Marty Ryder' from when Brian introduced him to Melanie. What I want to know is where the fuck they got 'Pancho' from?
