After the reveal of Barty Crouch, Moody took his flask back and cleaned it from the potion. However, Moody filled it with Polyjuice Potion again in 1997 some minutes before the Flight over Little Whinging as six people had to disguise them as Harry Potter. After a brief argument with Harry, who was initially refusing to let six people to risk their lives, he reluctantly gave a few strands of his hair to add into the flask to complete the potion, and Moody split the contents into six egg-cup-sized glasses, each for one of the would-be impostors, while warning everyone that the Polyjuice Potion tasted like "goblin piss". Moody himself did not drink the potion.
When Moody was killed and his corpse recovered by the Death Eaters, it is unknown what happened to the flask. It's most likely that it was desposed with Moody's body or was kept as a trophy by a Death Eater.
Behind the scenes
- The Noble Collection sells an exact replica of the flask, for around $30.
- In the novel version of Harry Potter and the Deathly Hallows, Moody simply took out "a flask of what looked like mud", with no mention it was his personal hip-flask, but the part 1 film adaption, the potion came from this specific container, with the content not shown due to the non-transparency of the flask.
- The film version shows the flask to have the top in the design of a human head with wings, which was not stated in the original novels.
- In the the film adaptation of Harry Potter and the Goblet of Fire, Crouch did not forget to take the potion from the flask while interrogating Harry, but instead he ran out of it. Also, Severus Snape sniffed the opening of the flask and was able to tell it was Polyjuice Potion.
