Those who remember Whisper as Pasta Batman can attest to the fact that she was never silver. She was grey. Grey from being used as a mere vehicle to express a selfish little boy's favorite things. And with her Missing Cat sign affixed to a clipboard instead of a tree, we're certain that no one will find her.
Thankfully, little Jimmy will always have a cat named after two of his other favorite things. God bless that Christmas Nitrous.
