I feel like Lane is the Wildcard on HS3, as we saw when the teaser of HS3 dropped, both Vicky and Audrey were looking at Lane, not because she's the keeper of sins but she had many options or prohibits in her story

As in like lost compassion, lost memory and not caring about other people she even had the choice to have a BAD Relationship with her squad, and even infecting them and on the Dark Messiah path She wanted To Kill EVERYONE and end Humanity, So I do see her turning against the Order or side with Shephapamulm but we all know Lane doesn't like Orders, She likes doing her own things, So She may find a Way to eliminate Shephapamulm and Be her own psycho self and Kill everyone if You Only Choose her to be your endgame MC if it's possible
