S2: I think [.....] betrayed [......] once [......] was no longer "his little angel"
No. 001 was genuinely completely taken with Gi-hun for most of the season......until Gi-hun was willing to sacrifice most of team X in order to "end the game".
No. 001's bubble was burst when Gi-hun decided this and he turned full evil again. Anxiously awaiting what no. 001 has in in store for Gi-hun.
Personally, I'm still not disillusioned. I believe Gi-hun was pushed so past the breaking point and his effort to do something against evil like 1%-ers having a battle royale with poor people......it's what I always wanted and didn't get from Hunger Games. And now I have it in epic fashion in Squid Game, even though Gi-hun and his remaining allies seem completely toast.
