If you just leave Oskar behind or never even find the hideout, Lady Jannath hosts an art exhibition in her manor. You have to do nothing, just show up and chat with the other guests and staff. It has some fun little moments and a hint that her taste in art might have changed in Oskar's absence, which I thought was funny. It's also a cute opportunity if you just want to roleplay some sort of social moment with your pixel-pals, although they are not super reactive to it. (It's the most missed opportunity for people to recognise Wyll in my opinion.)
That sounds interesting and yeah, it's sad that Wyll isn't more recognised. But I will do that next time for sure. Lady Jannath is so much better off on her own.
