When Nagisa died, and then when Tomoya finally remembered his father being a good parent, and calling himself pathetic. The killer was Ushio saying that the two places to cry were in the bathroom and in her dad's arms.
I was an emotional wreck between episodes 16 and 18, not even caused سے طرف کی specific events. I would suddenly remember a stupid scene from the first season involving Nagisa, then remember that she was dead, and then realise all over again about the five years that Tomoya had wasted ignoring his daughter. I kept imagining what Nagisa would think if she knew Tomoya was treating the baby she gave her life for in the same way he hated his dad for.
In the first season, it was definitely Fuuko being forgotten سے طرف کی everyone, then Tomoya and Nagisa finally remembering her and it's revealed that she was standing there the whole time. Also the bit after the wedding, where she's finally happy but everyone forgets her again. Although, the various scenes following that where she pops up suddenly did a lot to cushion that blow :')
I cried almost literally all of AfterStory episode 22 "A Small Hand." Though,half were happy tears.
But,one moment that made me cry the most was Nagisa's death.I almost choked on tears.Afterwords I had to ball up in my room with tissues and sing Dango Daikazoku to calm down.I am so glad she got to come back!I am getting sad thinking of it.NAGISAAAAAAAAA! *crying*
