Neville's struggles

The Nervous Boy
The Password Problem
Neville is notoriously forgetful. He constantly loses his passwords, gets locked out of Gryffindor Tower, and is bullied by Snape. His grandmother sends him a Howler when he loses the password list, causing him great shame.
The Potions Disaster
In Potions, Neville frequently makes mistakes. He turns his Shrinking Solution orange instead of green. Snape torments him, and he nearly poisons his toad. He is terrified of Snape, which only worsens his performance.
The Boggart's Fear
In Lupin's Boggart lesson, Neville's greatest fear is revealed to be Professor Snape. With Lupin's help, he transforms the Boggart into a comical version of Snape in his grandmother's clothes. He successfully casts Riddikulus, earning applause and growing confidence.
