Author's Notes:

Letter 26.1: Here.

Dear Anon,

I've hopefully defused her for the time being but I need you to make certain - with Spike's help - that the blackboards are erased, her notes from the past day are destroyed, and Twilight does not contact Pinkie within the next 36 hours in a private setting. Follow her around if you have to.

All will be well,
Celestia
