Time has passed and many things have changed. Twilight is a princess, his home was destroyed and then turned into a crystalline castle, and Spike has become much happier.
Spike himself hasn't changed quite as much as the girls though. He is still the same hight and weight, has the same personality, is same assistant, and has the same secret hobby.
While change can be a good thing; Spike desperately wishes to keep his foalish desires the same way they are now to avoid embarrassment, hidden.
Will Spike succeed in keeping his "Forever Foal" lifestyle from becoming discovered or will his deepest darkest desire suddenly become not so secret?
