 * Alice suffers from ADHD.
 * Alice is very excited about life.
 * Inverted: Alice is an Emotionless Girl

 * Parodied: A physiologist is determined to discover the source of Alice's genkiness and the result revolutionizes the human existence.
 * Deconstructed:

 * "I'M SO FREAKING HYPER" - Alice
 * Invoked: Alice drinks coffee and other drinks with high caffeine so she will always be on the go.
 * Defied: Alice tries to calm down her large bursts of energy, whether taking medication or doing a sport.
 * Double Defied/Exploited: Someone needs Alice to run really fast someplace...so they give her caffeine.
 * Discussed: "You know, Alice's hyperness would be perfect for this. She'd probably be able to kill the mooks without their ever being able to lift a finger."
 * Conversed: "Alice needs to lay off the Coffee, seriously."
