Advice From Twilight

Dear Twilight,

I wanted to thank you for saving me from that evil unicorn, and to ask for some advice. Recently our Twilight has been getting some cryptic messages from Ness, and were hoping you could unravel what they mean. All except for one of them appear to be written by someone else, and they all use red ink (at least I HOPE it's ink). The only message that appears to have been written by him, tells us to not reply to him, no matter what. If you can help us, we'll be waiting at Sugarcube Corner.

Your Friend,
Sunset Shimmer

What do you think of it?

It definitely sounds like him. I'll grab the others and join you at the mirror. Here's hoping that he hasn't done too much damage.
