Was Wonderland real?
The immediate frame identifies it as Alice's dream, but the sister's closing vision gives the experience emotional reality.
Why does Alice defeat the court?
Her physical growth accompanies intellectual confidence; once she names the judges as a pack of cards, their power collapses.
What is the trial parodying?
It exposes procedure without evidence: verdicts, rules, and punishments are invented to protect authority rather than discover truth.
Themes and What the Ending Means
Identity: Changes in size and memory make Alice repeatedly ask what remains stable about the self.
Language: Puns, literalism, and recited parodies turn communication into unstable play.
Authority: Adults, teachers, and rulers impose arbitrary rules while claiming perfect sense.
Growing up: Alice's body changes faster than her confidence, then finally becomes a source of resistance.
