what'll give away bolivia?

[Six-fingered Girl]

I'm still not sure about this as there seem to be clues pointing to both sides. The hair dye and genetics suggest that they're both blondes. I didn't get a good look at the pictures of Altlivia when she was younger - does she have dark hair?

In the picture we saw of her winning the Olympic gold medal in marksmanship she has blonde hair and bangs.

I'm looking at a screencap and I can't really tell - it looks sort of reddish to me, but maybe that's just my eyes. (Is this even the right place to be discussing this?) I suppose the question is, why isn't "Altlivia" (Olivia) re-dyeing her hair now that the blonde is starting to show through?

There's one picture on the mantel of the two girls, looking light brunette to blonde rather than red.

I always assumed Olivia was a light brunette/dark blonde who lightened the upper layer. Just because she's work-obsessed doesn't mean she has no vanity.

That answers my question. I just thought that in the vein of "what would give Altlivia away" - maybe it wouldn't be her actions, it could be her natural hair color showing through, as I've seen a lot of people mentioning. But since she seems to be a blonde, I think that theory is probably not going to pan out.

First I think Peter is the most suitable person to find out that she's not her...he is the one who spends the most time with her...Peter knows Olivia more than anyone else does...Now the things that will give her away is no different that any of you say...She is way more "fun" and happier than our olivia is,and that's normal since she had a good, drama-free life...Altlivia had never met John,never had a relationship with him and he never lied to her about who he is...This was the real reason our Olivia was carefull around Peter,she didn't want to be heartbroken again..She smiles way too much...Our Olivia hardly smiles...Altlivia will always try not to get caught so sometimes,like last episode,she will try to avoid solving the case they work on...Our Olivia always risked everything,even her own life,to find out the truth!!!She doesn't have a photographic memory,but I don't think that's gonna be a huge problem as she is very focused on her mission and I don't think she would compromise to get exposed by something so stupid...But details make the difference right?OBSERVERS...It would be great to be given away by one...but observers are all over the pattern so she must have studied them,right?the only way I can think of is if September leave a code for Walter but I don't think that's gonna happen...Sam Weiss could drop by her house and expose her...But we all know that we can't trust him anymore...!
I'm 99% sure that Peter will FINALLY wake up and see that she's not ourlivia...he will take notes,he will work on it,he will collect evidence and when he thinks it's the right time he will trap her somehow and expose her!!...of course there's the chance our Olivia comes back...Maybe that will be fatal...maybe that's what will wake peter up...I don't know...I just miss Fringe...!!!I wanna see a new episode now
