Sam's Story: After you zipline from the fire station, go inside the ruined house. The note will be on a dresser left of the workbench. Be sure to grab it as soon as you jump off the zipline, as you won't be able to come back for it later.
Looks like it's the end of the road... The fucking batwing's waiting! As soon as I peeked outside, it swooped down from the trees! I heard the trees crash and don't remember what happened next, I think it tried to grab me and missed, nicking my side with a talon while I backed into the ruins. I put pressure on the wound, but can't stop the bleeding...
Tail, if I don't make it, stick a knife in Nose's gut for me.
