After the events of Crusaders Of The Lost Mark, Pipsqueak and Diamond Tiara have a little conversation. Surprises are shared, secrets are learned, and a scheming best friend is up to something...
The Royal Guard has intensified their training regimen after countless attacks on Canterlot. After months of hard training, they only accept the best of the best. Pipsqueak signs up to join these elite soldiers in order to protect a certain princess.
(An indirect sequel to "Spoiled and Sour", familiarity with it and its predecessor is encouraged but not necessary.) Diamond Tiara wants to officially introduce Pipsqueak as her coltfriend, a tough sell considering who her mother is.
