The surprise party for Flint was first written for the end of Chapter 5. Originally the parents were going to come straight home from the airport and Cass hadn’t told them about their transformations yet. Flint had been giving her flak for keeping him inside their house all week, and Cass realized that her brother needed to be with his friends again. She invited them all over after the Argo situation ended. The parents then arrived at home after the party, finding Cass, Flint, Noah, Morty and Jen waiting for them, and everybody explained what had been going on.

That ending didn’t seem like the natural way to deal with the dynamics between Cass/Flint and Cass/Parents, so it was thrown out. I really liked the idea of getting some closure for Flint’s “grounding”, though, and this party feels like the right thing to do after Flint’s first flight and first personal victory at Attic High.

This is the first chapter of UTC to show events that happen on two different days. My writing style for a very long time had been to begin and end a story during a single day, with no interruption or time skips. It was never deliberate. (Except in Seven to Seven.) It’s just something I did. Chapters 8 and 9 helped knock me out of that mode of writing.
