So aside from Ougis hands being covered in gloves like when they first showed her as a boy, the argument between Hanekawa and Ougi was interesting this episode. Really felt like the foreshadowing was everywhere this episode.
Also, this is just speculation, but am I the only one being lead to believe that Ougi is an apparation of Araragi just like the tiger was for Hanekawa? She keeps saying things over and over that makes me lead to believe this.
"I only know what you know" which is similar to the Hanekawa "I don't know everything, I only know what I know" saying.
