UNSPECIFYED CHAPTER: Big Sister is Always Watching
At some point, Eleanor Lamb tells the other big sisters with excitement: "The big sisters are going to Columbia!". Which they do and sally has to fight a lot of vigor Junkies and what not; Handymen, Joalwí's playable friends, and one more special vigor Junkie called "The Charger" he has stag horns on his helmet and floats on a little twister all the time, which allows him to move around and dodge pretty fast and his attack is to charge with the Storm Fury vigor.
Another specific sequence of events: Sally fights a very loud firelady (fireladies combine the skills of the Fireman and Zealot to a certain degree; in which she attacks with fire but can also teleport, much like a Houdini Splicer); who yells constantly about her so hated "sodomites" (in fact, all of the vigor Junkies would curse the "sodomites" in any given opportunity [Sodomites being anyone who isn't from Columbia]). She's a thought and extended fight, keeping herself alive and pulling tricks and traps over Sally; she also reveals at some point that her name is Tanya.
The big sisters have as their meeting point, the ship ducks at Finkton; in where Sally meets with Eleanor once again. Eleanor shows very special favoritism for Sally, and has the next conversation with her.
Eleanor: "you know.. Mothers are vastly irrelevant; I never listened to mine, I decided to drown her instead. You shouldn't listen to yours either; I see your potential, you should listen to me instead... always ...let ME be your mother"
Sally: "what are you talking about? Do I have a mother?
Eleanor: "oh...! you don't know..? ...of course" –looks away while being struck by memories that make everything clearer-
Then they are suddenly interrupted by another big sister who yells: "We're getting surrounded" And they effectively are.
Eleanor: "come, all of you; let's jump off this city"
Another big sister: "We are hundreds of feet in the air"
Eleanor: "just take my hands, and the rest of you make a chain and jump off with me"
Another big sister: "Oh! Of course; we can teleport safely when we're close to the ground"
Then they have a lot of fun freefalling and doing circles and all sorts of flips and while they all are in a circle holding hands together, a big sister says this: "This was a lot of fun and all... but I don't think we've accomplished a lot."
Eleanor: "Yes we have... more than you could ever imagine... we got some Intel ... About Elizabeth and the most powerful Big Daddy ever created... they were not properly bound... I mean, of course; that technology left Rapture before it was fully implemented ...before Gilbert Alexander. That Big Daddy needs a new little/big sister ...and that's gonna be me...
