Please stop using the words 'bad ass', it reduces Ellie, one of the most rounded characters in any video game, to a b movie clique. In that situation, what else would she do? Think about this carefully before just conjuring a scene in your mind that fits the scenario for THIS particular character. Would she lose it? Would she be cowering in the corner? There isn't many options other than to be who Ellie has been throughout the whole game. Bravado fits her personality, especially when there has no other option. Context changes everything. Ellie finally showed her vulnerability when her antagonist was dead and no longer a threat. She falls apart in Joel's arms because the space to do so opens up. That letting go leaves her numb for quite some time, leading to a scene that seems to have baffled many people for some reason. Just after being attacked and in her mind about to be 'raped', having finally let the act drop and fallen into the arms of her Father, we move into the scene at the bus station and people ask: 'Why is Ellie looking unhappy?' No, seriously, I saw so many Let's Plays of people not connecting the two scenes properly and being confused. 

Everyone already explained to you what her fear was. 

Eh, getting older is irrelevant, because everyone is getting older. What you haven't explained is how she's supposed to act. Compared...to...who? If not an average 14-year-old girl, then who?

 I would think if this character was smart she would play it cool, and wait for the right time to strike, instead she does everything in her power to get killed, but hey everyone has different opinions. 

I already understand whats her fear is, but like i said before, for me it hurt the story a bit in my third pay through. maybe i'm getting older and more judgmental.

Continuing to repeat "for you" doesn't change the fact that you're on a public forum and people want to know why >>>>>YOU<<<<< said what you said. 

Now, to what matters, it is contradictory... You say "mo she acts like a average 14 year old, most 14 year olds have fear of being alone when they have no friends, loving parents or love interest" then say "sh acts  like a average  14 year old with no fear, and that takes me out of terrifying world that supposed to be last of us, and i honestly think its the one thing games need to take it to the next level on, because its makes characters   more human, and make the story way more believable for me". This issue here is we aren't dealing with an average 14-year-old girl, and unless you've lived through something like she has (which would be a first for any living human), then it doesn't make sense. So, the placement of expectation remains a head-scratcher, because you cannot relate to those immediate feelings. And, despite all that, saying she has "0 fear" is completely inaccurate. 

When I was 16, I saved up and took myself on a package holiday to Africa. I met up with the group of people who were also on the same safari holiday. Early in the second week, we were taken to a lodge in the middle of no where. It was a lovely place with giant moths on the lawns and humming birds flitting from flower to flower. I was so excited that I decided to step outside of the lodge's grounds and soon found myself by a riverside, surrounded by long grass and 'upside down' trees (that was the local name).

After walking further along the river I came upon two men, both at least a foot taller than me, wearing a uniform of some kind and hats with an elephant badge at the front. I was 16. I had no idea who they were. I was nervous but decided not to run because both were carrying rifles. So, calmly I began a conversation, my voice steady because I feared sounding afraid. They spoke in thick African accents, in clipped English, but I got the gist of what they were saying because they kept pointing at my binoculars. They wanted my binoculars. I told them they weren't mine, they were my parent's (I wanted them to think I would be missed. I was a smart cookie at 16), and pointed up the hill to the lodge. They looked at each other and smiled. 

I began to walk back towards the lodge, talking all the time about how amazing Africa was. I mentioned the upside down trees, the fact I'd seen a cheetah the previous day and that I'd not seen many animals around here today. One of them then told me I wouldn't ... because they 'shoot small animals'. Again they smiled. Looking back at that scene as a 60 year old, I can see they were likely winding me up (but that's still only 'likely', not 'definitely'). The long walk up the hill felt like the longest walk I'd ever taken because the closer I got to the lodge, the further back they fell. I turned at one point and asked them 'will you be here tomorrow?'. They never said anything. I continued, 'Maybe I'll see you tomorrow and you can tell me about this place.' I finally got to the top of the hill, rounded a corner til I was out of sight and then ran like fuck.

I was terrified throughout, shaking inside, my heart beating like it's never beat before. When I had my back to them, as a 16 year old boy, I was convinced they may shoot me. Think about that. But I stayed calm, collected and only when I reached the lodge did I turn white and begin to shake. It wasn't bravery, it was self preservation. 

I enjoyed the story, but i dont't get what that has to with ellie character, she been through shit, where she doesn't fear death anymore.

You don't see the connection, or the don't want to see the connection? I think it's clear. Ellie's bravery when she was in that jail cell was self preservation. You're making the mistake of thinking she's a 'bad ass' instead of considering her options. That's why I said think carefully about what you think she would do.
