If she did then... wouldn't it be easy to get rid of Ougi? Unless both of them cooperates... but then we already know that Ougi tried to kill Kaiki in Monogatari and that Izuko is closely related with Kaiki from their senpai-kouhai relationship.... well from Tsuki we know that Ougi in the end will face against Araragi but what about the rest? Kaiki, Kagenui and Ononoki, Meme who's been missing since Bakemonogatari.....
Since the next series will be Kizu I feel like it won't reveal anything on Ougi and more of just the backstory of Meme and Kiss-shot. Maybe we can get reasons on why Meme disappeared for so long...
Ah~ this series main points is the dialogue but the story itself is so interesting....
