The head writer (story editor) has almost always written the two-parters, and it's been that way since season 3 (the only exception was The Cutie Map, as that was written by Larson and Sonneborn, only featuring a story from McCarthy, as she was still the story editor for that two-parter and Bloom & Gloom, while Larson was the story editor for the rest of the first half of s5, IIRC)
