Ah! I had most of the words, and even thought it might be from the trainer scene in TGG but couldn't get "sparkling form." Well done Pamela!
Is yours "I am on fire!" ?
Ha, glad it wasn't just me! There were definite words that sounded Rickman-esque... "Yep" (when he was talking to Archie), "Do people like me?", "Our entire species...", "When one of them's dead"... And probably more! Those are just the ones I remember off the top of my head. Always make me laugh :-)
