Naturellement, my friend.

I spoke to Oswin-san earlier; it seems your partner is telling the truth. Oswin-san woke him up last night because he was trying to interrupt this Demon meeting you all apparently engage in, but he missed his window of opportunity - instead of putting a stop to his activity as the Incubus, he shook him before the Maddened could strike. They didn't hit him because he was already awake.
