Hermione is perhaps the most normal of the trio, but shows enough contrast in that she seems to display no real opinion on the events, acting either as a bystander passing comment, or a willing accomplice in Harry's mischief. Which is quite different from the novels. Hermione's intelligence is briefly mentioned but little of what she displays in the books is seen. In the secret butterfly scene she cast a spell on Ron Weasley.
In 'Harrys Nightmares', Harry had a nightmare that Hermione was addicted to amphetamines, and tried to kill Harry and Ron with a hammer. Her favorite wizard swear word is "Swish and Flicker".
