This comes toward the end of episode 1, when you're making the alcohol for the drill.
This works best if you go into the options and turn the subtitles ON. Also, be careful because the further along you go, the more often you'll hear Emmett's father make a statement that is designed to trick you. Also (rather annoyingly), I noticed his father say something with the same code word for what Emmett was saying. That's pretty much an instant loss for some reason, but again, don't worry. Reload the save and start over.
The bad part is that this is missible. Worse, you can't save during the scene. The silver lining is that the game makes an autosave at the very beginning of the scene. If you make a mistake, you'll see the fire go out and Emmett will let you know that you need to listen for his cues. If that happens, pause and reload that autosave. I had to restart a few times and still got it.
Of note: the achievement doesn't pop until after the cutscene finishes, so don't worry if you did it correctly and are still waiting for the pop.
Emmett will be arguing with his father, and you'll need to perform one of four activities in the correct order. Emmett will be giving you hints, so pay attention to the words he emphasizes. There are four stages, with the last one being fairly rapid fire.
Release Pressure Valve = "bladders," "bags of gas," anything to do with releasing or pressure
Stoke Fire = anything to do with heat or fire
Turn Electrical Crank = "spins," "shock," etc.
Bacteria Food = "microorganism," "eating," etc.
