S4: It's a dragon affair! Spike will find a group of dragons unlike those he has encountered before.  This group of dragons will demonstrate a moral code and nurturing environment not unlike that of the ponies that Spike has become accustomed too.  After spending time with these dragons spike will learn things about his past heritage and secrets that will shock him.  

Yet again Spike will have to make a decision to either stay with his new found kindred or return to Ponyville.  What will he do??? ...during his contemplation cue the sea ponies! "Shoobie doo shoo shoobie dooo"
