Brink's machine glitch in The Dig

After you show the eye part to Brink and skip the cutscene, you can use the eye part with the slot. When you do that, there's a good chance Low will move and use the eye part as if he were right in front of the slot. This doesn't save time because you still need to walk to the machine to pick up the eye after you've used it. However, it might make Brink's movement manipulation easier. After you pick up the eye part, there's an unskippable cutscene where Brink goes berserk. During that cutscene, Brink needs to move to a certain position, so you have to wait for him to do that. However, when you skip the "using the eye part" cutscene at the right moment, Brink will move to exactly that position, meaning the "Brink going berserk" cutscene will be shorter. The downside is that skipping the "using the eye part" cutscene it at the wrong time will make the "Brink going berserk" cutscene longer.
