Saki Konishi's Midnight Channel clip ➤ A convention of Persona 4, characters who are thrown into the TV World have a broadcast to real world televisions at midnight when it's rainy. Saki's is the first that the characters notice. It's choppy and supposed to be difficult to find out who it actually is, but in canon Yosuke is able to pick up that it's a girl in a Yasogami uniform, and later notes after her death that he had a feeling it was Saki all along, he just didn't want to admit it. After Yu telling him in Recolle that Saki is someone important to Yosuke and that he thinks something bad happened to her, it won't be a difficult connection for Yosuke to make.
