The Master of Ceremonies [Spoilers]

Has anyone found a way to make him perform the ritual, or is it impossible (hard to know for sure unless a dev says so I guess)?
I had an idea of waiting for Zoe behind the effigy if this is possible, but I haven’t been able to find a way yet. (obviously could just go round, but it would be fun to do it suit only or somesuch).

Approach the blind girl disguised as janus and with the dagger in your inventory and you will see the option to start the ritual.

Sorry, this is another ritual, the ritual to burn an effigy with Zoe Washington inside it.

I have tried many times too. I think it’s kinda like Marrakesh at night, no way to make Matty go to the meeting without leading him there yourself.
