"No point of trying. All Cookies are too small and weak..."

Story
''Timekeeper Cookie once used to snip away countless timelines, but has now fallen into an irreversible feeling of futility. No matter what happens in the time rift, the Cookie only chuckles quietly, thinking it's all pointless, and flees the scene on the broken Sonic Embroider. Perhaps, this Cookie has seen too much...''

Pre-Pull

 * No point of trying. All Cookies are too small and weak...

General

 * Why change time? Because I can and it is fun.
 * The end justifies the means...!

 * The TBD doesn't need to exist. Don't you agree?
 * It's just impossible for a Cookie to manage the time.
 * Whatever. I don't care anymore.
 * Fix the time? Why should I?
 * All I know are just little pieces of time...
 * How convenient it would be if there was only one future.
 * The future is changing this very moment.

Tired

 * Why do we even need TBD? They're the ones ruining the time!
 * It's nice in this time pocket... Nothing ever changes here...­
 * It's too late to turn back...
 * Time pockets are where all forgotten times linger.
 * I'm not even the Director anymore!

 * Someone will help you get out eventually! But it won't be me.

Trivia
