Hannah's first Moment of Awesome is her actually entering the Spook House despite how terrifying it is. It immediately shows that she's not a complete scaredy cat like Jimmy assumed she was.
Everyone Hannah meets on the Fright Side helping Hannah get back at Jimmy, Bert, Daryl, and Katie for trying to scare her.
Max getting full on Papa Wolf on Harry, when the latter accidentally suggested ordering pizza with garlic. The skinny vampire overpowered and nearly choked a more bulky werewolf. Thank God Orson was there.
Jimmy's Revenge
Hannah Took a Level in Badass in this sequel. She manages to use her creativity and love of Halloween to (albeit unknowingly) outwit Jimmy's attempts to sabotage the holiday.
Jimmy managing to scare Bug-A-Boo of all people! And by accident to boot!
For some reason, Boozle's "sounding the alarm" moment.
Katie saying she and the other teens deserved the scare they got in the last movie after the way they treated Hannah. Just seeing a teenager willingly admit that they were wrong about something is awesome in a maturity sense.
