Joel And Tess - Tumblr Posts
The more I think about it, I can't get over the scene with the cops at the beginning of the game; it's so powerful, real, and raw. There is so much happening in just one minute.

First, Ellie knows her 'infection' is going to be revealed. She needs to act quickly, and even though it's against her nature, she must do this. She doesn't want to, though; it bothers her. It says a lot about her as a person when, a few seconds before stabbing the guard in the leg, she apologizes to him. The guards are there to probably kill them, and she says 'sorry' before hurting one of them out of fear. The kid is unbelievable.

Then it's Joel and Tess, so ready to immediately fight back, moving quickly and efficiently without hesitation. They are used to this; it's not the first time they have had to deal with something like this. They know there's no other way than to use violence, making Ellie realize what kind of people she's been sent on a mission with.

She can't handle this. She feels sick; she doesn't enjoy seeing people being killed—not even the bad guys. She's a good kid; violence is the last thing on her mind. This is one of the reasons why I'm not fond of the whole "Ellie has a violent heart" thing in the show.

They really messed up with this. Making such a sweetheart of a character someone who enjoys seeing a man being beat up to death only to excuse Ellie's ptsd behavior in Part 2 is not exactly wise. The Ellie we all know was not 'activated' by Joel's aggression, quite the contrary. She was shaken to see this kind of violence.
