The alleged deal ultimately would have left those outside the alliance trying to scramble in the opening weeks to forge bonds, and at a distinct disadvantage thinking they could work with people who were already working elsewhere.
It’s a feat that would be a lot more impressive had allegations of pre-gaming between Cody Calafiore and Nicole Franzel not been floating around both inside the house and on the internet.
The explicit details aren’t known, but there has been enough chatter from houseguests that it seems likely from my perspective that Cody and Nicole had pregame alliances and intel on who else was in the game, and were able to make some alliances accordingly that benefitted their plan for a Final 2.
