Actually, it was crowded that day, and we were split across two tables. It seems the tragedy unfolded at Yamame-san's table. Thank goodness I was at the lucky table! :-)
By the looks of it, that means P-san had to share the table with Yamame AND Flandre (based on the last comic). So, was that table basically the torture-table or something? As for the poll, probably Kanako-sama or Sanae-san. I imagine you could learn a lot of interesting things chit-chatting with a goddess...
