Stuck on chapter 7

Answer from: Sirei
Tap slow, just hit the walk button quickly and short. Also I looked where her eyes were, don't go if she looks at the hostage. It takes time but slowly you should get to it, just don't move if she talks to you.

Just walk to her but then she talks to you, you MUST stop then the conversation options will appear.Just do this again and again. Sorry for my bad english :(

There is supposed to be a zombie at the top of the staircase and there. Should be an option to speak to Brend but if you get shot, it seems you get trapped in a glitch when you try again. No options or zombie appears. You just get shot over and over.

Ok you get shot and no matter what i do theres never a zombie or option to speak so what do i do now

No tapping! Tapping makes Lee to walk still. You have to hold the button till she starts to speak than you can open the dialog by aiming on her stomack. Done it 3 times and here you go and here comes the zombie.

What I did was wait for her to look at the hostage, the second she looks away from the hostage I tap forward twice (you could probably do 3 times, but I wanted to be safe). Then stop the second she starts to talk or seems like she is about to talk. Obviously do not call her a bitch or tell her that you're gonna kill her. Eventually, the upstairs zombie gets her. This has to be the most annoying task in any video game ever. I hate slow tedious parts where if you make one slight mistake you have to start all over again. The designers should have put instructions like "watch her eyes" or something to give you a hint.
