You look at her as you keep walking together
You come across a half ruined building
Abby: we have to go through this building now
You nod and follow her. After a few steps in, Abby stops.
Abby: Spores...here take this mask, you'll need it if you don't want to turn into a murderous infected. I don't specially fancy having to shoot you if you do get infected so please just put it on.
You do as you're told
Once you're out the building and the masks are taken off Abby feels a bit chatty.
Abby: So , do you like dogs?
