Nah. I did forget about Mraize's showing up in Urithiru beyond the end in WoR, but I don't think I confused it. I think I just assumed that both tellings of the Girl Who Looked Up were in the theater, and as a result assumed the scene took place in Urithiru. I do feel like I remember Wit's first appearance to Shallan being in Urithuru, not the capital, but I could just be confusing it with his actual first appearance which, if I recall, was outside of one of the Oathgate platforms.
