A/N: This is flawed, I know, and not truly in keeping with the theme, but I think it captures Neville quite well. For CodenameJellybean!

Neville wished that, when Ron's scream awoke him, he ran over to Sirius Black with bravery previously unheard of and set a body-bind curse on him. He wished that, with Black suitably immobilised, he started yelling at the escaped prisoner for trying to kill one of Neville's own.

Then, he would've seen the slip of paper crumpled in Black's hand, the passwords Neville himself wrote. This would've set off a flame of rage so strong Seamus and Dean would've had to hold him back to stop him pummelling Neville with his bare hands. After Neville had launched an impressive range of expletives at the powerless Black, he would've carried him down the stairs. A thirteen year old boy carrying the most wanted criminal single-handedly would've earned him respect for life.

No-one would make fun of him then, he'd be a true Gryffindor.
