SPOILER Questions for Episode 3 final act

[StrawberryRainPop]

What happens if you dont fight the first 2 zombies in the house you and clem go to at the rail way tracks near the end?

Will she shoot for you?

Also, for the 3rd zombie in the room with her, if you dont unlock the door, will she defend herself?

[PanStrife]

Clem shakes in fear and doesn't shoot - you get eaten. With the second I think she gets killed.
