After Spike felt left alone and full of rage, he left Ponyville without telling anyone. Somewhere in the mountains he met Garble. At first they were just snarling at each other, but then they both realized they were in similar situations. Garble ran from Ember’s “Dragon Riot”.

Together they decided to just go wherever they wanted to (ending up in situations like this, scaring little kids). Was Spike turning evil?  
Slowly the two dragons started to feel attracted to each other…
