I'm sending you to supervise the preparations for the Summer Sun Celebration
You needn't worry at all
And, I have an even more essential task for you to complete: make some friends!
You are entirely prepared for what I'm about to assign you
I would never keep a secret
I'm prepared for this day
Nothing could possibly go wrong
It's all going exactly according to plan
I am fearlessly confident in your ability to succeed, Twilight Sparkle
Your chance of failure is non-existent
These hit harder because we've heard her actually say some of these in the show.
And they were lies.
