About the finalization of the tower card, we're pretty sure that shuu and kanae are the falling pair, but the flash of lightning most likely is represented by Hairu's T-human quinque, which shot bolts similar to arima's. I suppose that eto or kaneki causing the helicopters to explode could be the fire? Kaneki destroying tsukiyamas escape helicopter in a swath of flames could represent the fall of the crown (shuu as the heir) Either way I'm scared for what the star could mean next arc.
Oh I really like your interpretations about the Tower card! They make a lot of sense in the context, especially with Shuu as the heir.
But the Star has a lot more of a positive meaning than the Tower, so it can’t be any worse than what we’ve been through this arc :O
