Dani Ramos: How do we win?
Grace: We win... by keeping you alive.
Dani: What did you tell them?
T-800: I told them you coming here makes this place unsafe for them. Also, the day I warned them might come, has come. My past has caught up with me. And...I won't be back.
Sarah Connor: I'll be back.
Grace: Who are you?
Sarah Connor: My name is Sarah Connor. I've never seen one like you before. Almost human.
Grace: I am human.
Grace: Why do you care what happens to her?
Sarah Connor: Because I was her.
Dani Ramos: Two days ago, I had this nice, simple life. And now it's a nightmare.
Sarah Connor: My name is Sarah Connor. August 29th, 1997 was supposed to be Judgment Day. But I changed the future. Saved 3,000,000,000 lives. Enough of a résumé for you?
Grace: No. You may have changed the future, but you didn't change our fate.
Answer: Skynet and Legion were both developed for identical purposes: defense network artificial intelligence. It stands to reason they would both evolve in similar ways. Since both Skynet and Legion were fighting a similar human resistance, they both developed similar infiltration units.
