[A costumed character known as "The Mockingbird" is sitting bound to a chair, and gets punched in the face]
[Another character in a bird-like costume is revealed to be interrogating the Mockingbird]
Finch: Ready to talk, Mockingbird?
[Mockingbird spits out some blood]
Mockingbird: (mocking) "Ready to talk, Mockingbird?"
Finch: Aah! I should've seen that coming! Scout, see if the coast is clear!
[A bird-costumed character wearing goggles and a speaker-phone searches, then turns toward Finch]
Scout: Coast is clear, Finch.
Finch: Good. 'Cause I'm about to kill a Mockingbird!
[Mockingbird clicks a button on a detonation device, which breaks his bindings]
[He then kicks Finch in the crotch, then whacks him with the chair, and kicks him a few times more]
Scout: Jem! Jem! Use your gemstones!
[A character in a red bird costume shows up]
[Jem fires beams from the gemstones on his wings, effectively killing Mockingbird before he can get away]
Scout, Finch, and Jem: Yeah!
[The group celebrates, then cut to a classroom]
[It's revealed that this was all part of a report]
Student: And... that's my book report on "How to Kill a Mockingbird" by Lee... Harper... Oswald or whoever...
Teacher: Couldn't even spring for the Cliffs Notes, huh?
[The teacher whacks the student upside the head]
