Think about it. The scar was never ever explained how she got it so it must be important. Like in uncharted whhere drake just wore a necklance unexplained before with a ring but was explained in unchharted 3,
So that scar mihht be important in a sequel. Like whhat if her scar is important like harry potter and is why she is immune other than thhe mutation and maybe a curse drake let out did it
Fireburn12that is probably true, but I think she got the scar when zombies attacked her in the Mall or from when she was younger, Reason why I believe its true is because in an interview the person giving the interview asked, I couldnt help but notice that destinguished scar on Ellie's eyebrow, anyreason to how she got that? to which the creator of the last of us : Niel Drukman responded, Yes but were not going to get into that such as he wanted to keep a secret for something, such as a sequel, or a DLC, or something....
