Not every other clan, just Piranas, Nightmare and Montana. The evil clans. And at most, the speech bubble with the word 'who' in it leads to a total of four places. Uppers or Zlatar corp. seems to be confirmed, and what looks like Fang Pi monastery.
Also, the middle minion of Nightmare. Is that supposed to be Glorg? Oshitsune? Someone I completely overlooked?
