Elsa

 The question "Can I pretend like Elsa?" will remain with me to the grave. Here she is, deep in Grandpa's garden, preparing to cast her spells and freeze all within range.

 "I am your queen and I have spells."

 "Now you are frozen."

"Now you are dead Daddy, because I am Elsa and I have spells and I froze your heart."

Thanks very much Elsa...
