I guess the sequencing of the anime is good with this one because if some events are inserted in chronological order then it would be a very heavy first episode. It would make the watchers time to breathe from the tense and heavy atmosphere. This episode is where Iroha requests a prom event. She has really changed, but she’s still as cheeky a kouhai as ever. I won't spoil much on what Yuigahama is thinking, you'll just have to guess from her expression since the studio manages to convey it well.
