Whereabouts of Auctioneer's Hammer (possibility already given that Excelsius destroyed, probably left at that, though I wonder how they ended up convicting him)

Where did Rosie Ringer's and Excelsius Winner's burns come from (unanswered question I am satisfied without having an answer, though I wonder how Excelsius got a burn mark in that location in that shape. Sort of like how we're left wondering how Kristoph Gavin got the devil scar on his hand in AA4)

Will Ian Sideman play a future role (he didn't, no reason for him to be involved with the events of the last case but I thought it strange for him to be given a name and not used at all after. For comparison, I would've been satisfied with Alf Aldown never being given a name and just being referenced as "Rosie had a lover once..." if he weren't in the last episode)

Why was Kay at Gourdy Lake the night she got attacked (maybe I just missed her being given a reason...but I thought it would be strange for her to return to a crime scene the night after a crime happened. If this was actually unanswered and I didn't miss anything, this would be a considerable plot hole in my opinion.)

Who were the other attendees of the illicit auction and what was the international connection - since Franziska von Karma was sent by Interpol (it just seemed like something domestic police would care more about than interpol, but it would make sense if the Alif Red statue was in Borginia before. Other than that, it just seemed unusual to include Franziska in this particular case)
