Thad's going to have two memories to go into; both connected by a hub of sorts, represented by a video monitor lined hallway inside Craydl. All the monitors will have something playing on them (some actual memories of his, while others are looped feeds of things he was taught about the Flash or Impulse), but only two of them will actually be gates that can be entered.
1. Speed Force Battle - While masquerading as Bart Allen, Thad took a dying Max Mercury into the speedforce with the initial intent to save him by having him reconnect directly with the force itself. But as Max goes on about how much he appreciates everything 'Bart' has been doing for him over the past month and how much he cares for him, Thad has a complete breakdown, reveals that he isn't Bart, and threatens to kill him. Despite Max attempting to talk him down, Thad tries to kill him anyway. Originally the only thing that kept him from going through with it was the real Bart coming on to the scene and stopping him, and finally succeeding in talking him down.
But the memory will be altered so that Bart doesn't show up, and the goal won't be to keep Thad alive but to instead stop him from killing Max (which could cause a mental shut down), or to find the mental generators before he can kill him.
2. Confrontation with President Thawne - Before being pulled to this universe, Thad had attempted to confront his creator. This is an incomplete memory that the generators will attempt to have end in his death. While Thawne himself wouldn't be too hard to take down (as he's just a normal human), he does has the Science Police at his beck and call.
