yes ^^ elle will kill joel in the end before he turns then we will play as her in the sequel, she will be 20 year old cause they won't have you play as a kid.TheGuardian03
I carefully looked at the trailer again....and you're right.
**Possible SPOILER below**
[spoiler] After you take a look at the scene where she points the gun at him in the end of the trailer, theres another scene before that where she's running towards the camera in the forest...alone and wearing Joel's jacket along with his shotgun.
But who knows, we don't know the origins of the disease and if theres even a cure. Perhaps Joel finds a cure through his contacts.
But goddamn it, you're right. [/spoiler]
