The Last Of Us Walkthrough Part 47 – Chapter 7: Tommy's Dam (The Plant)
Once inside the town follow along with Tommy and Maria. Follow them along, listening to what has been going on here. They apparently got the electricity running again, no small feat, but then a turbine broke down. They will approach some people with horses. Approach the horse on the left as Tommy goes to the one on the right to help the guy there. Talk with Ellie to learn when she learned to ride a horse. After that, you can pet the horse on the flank if you want. Just keep with the group after that to make it to the plant. Here, Maria and Ellie go to get some food while Tommy and Joel head into the plant.
Follow Tommy into the plant and into the next room. Talk with him when he goes over to the duffel bag to give Joel something from their home in Texas. Look at it then hit “triangle” when you are ready for things to move on. Joel tells Tommy he wants to talk with him privately. Tommy agrees to do that just after the check on their people working on the turbines.
Follow him up the stairs but then go to the left and into the room at that end. You will find some Crafting Items ahead of you and to the left on the desk in that room. If you turn around and look to the right of the door you will see a chair with some Supplements on it. Now head back out of the room and follow Tommy outside
Cross the area with Tommy as he tells Joel about the town. On the far side you will find a dog, Buckley, laying nearby the building. Interact with him to pet him. Tommy will be standing by a door leading into the next building. Look to the left of him to find some Crafting Items on a crate there in the grass.
Follow Tommy into the building. He will give a quick introduction to the engineers working on the turbine. Take a moment to grab the Crafting Items from the far side of the table and the Supplements sitting nearby. There is also a Workbench to the left that you can use to upgrade some of your weapons. Be sure to also look at the first edge of the control console. You will find a training manual for the Smoke Bomb. Upgrade, grab the manual then head over to Tommy and watch them start up the generator.
Before you follow him over to the far end of the walkway so the two of them can go talk, head down the stairs and over to the far end, the ground floor, below where you entered the Turbine room. Look around the room there to find some Crafting Items but the main thing is in in the locker opposite the door. There you will find a Firefly Pendant. Only after all that do you want to head for the far end of the room from where you came in. Tommy and Joel have some things to talk about. The conversation does not go too well. It is just after that the town comes under attack by Bandits.
