Walkthrough
The Seventh Chapter will begin with Tim and Pikachu back at Home, with Pikachu having another dream about when Skorupi Attacked him and Harry, as well as the car accident Harry had before he suddenly disappeared. After waking up, Tim and him will head to the Baker Detective Agency. Once there, you will learn that the Locket Harry gave to Buneary also had a hidden camera within it.
After developing the pictures within said Secret camera, Mr. Baker will notice Ryme Wharf is the location where the pictures were taken. With this in mind, Tim and Pikachu decide to head there next in hopes of learning more about the production of R, as well as looking to Find out what ultimately happened to Harry after his car accident. Before they do, however, Mr. Baker will insist they take Accelgor with them in Case they need help; Accelgor will carry the developed photos from the Locket camera. This is the first time you will have any type of aid outside of Pikachu for one of your Cases.
Once you reach the Ryme Wharf Shipyard, you will need to first determine what the man with blonde hair (the same you will see conversing with Keith on some of the film) was handling in the photos. By viewing the photos (thanks to Accelgor) and then gathering some Eyewitness Testimony, you will quickly determine that the man was handling none other than the Substance known as R. On top of this, it appears as though the Machine producing R is found within one of the warehouses, seen in another of the photos.
After determining what you believe the Blonde-haired man in the photos is handling, you will need to Find the warehouse where you believe R was being created and stored. In order to do this, you will need to collect more Eyewitness Testimony from everyone in the courtyard (sometimes twice or even three times with some characters as you learn new things from other witnesses), as there are a number of different warehouses in this area.
By doing this exact thing, you will learn that the blue containers that are handled contain food, the red containers hold oil, and the green ones contain machinery. On top of this, with the help of Machamp and Rattata, specifically, you will learn of some food that was dropped that had a very weird smell to it. Based on everything you've learned thus far in the game, it's easy to determine that said food was most likely contaminated with R.
After obtaining enough Eyewitness Testimony from the Pokemon and workers in the shipyard, you will determine (based on the shipping containers it holds) that the warehouse you need to investigate is found in Area A of Ryme Wharf. After figuring this out, you will need to Find a way to Infiltrate said warehouse. Thankfully, once you reach said area, the next Fast Action Event will take place, that same that will see you easily get within the warehouse in question.
