A lot of people ask about that one. That scene is only about 5 seconds long and is presently only on the patreon version. You have to get killed to get it.
There are two nsfw scenes (both planned, not yet implemented here or on patreon) with him in the cage. One with Ramus and Zephyra in Club Seamus and the other is with the blonde guy you haven’t met yet.
One other scene with bondage is planned with VT and Brontes. No cage though.
Updates to the public version have stalled because my original plan to add quests to the left side of the map (before you can go outside through the chapel) has changed. I may start keeping the public version a few months behind the patreon one. If I do that there will be monthly updates here for a long time.
