As to the original theory: You don't send high-level operatives on a suicide mission, especially when one is of less than perfect reliability.

Another interpretation: They'd been moving up the train, toward the front. Adam tells Blake to move on to the next car, the adjacent car farther forward, while he sets charges. I propose that the charges were to blow up the train after they stop and unload all the Dust. A point in favor is that all the cases we see didn't blow up, so clearly properly packaged Dust is less volatile. Blake's question about the crewmembers is about her, not the charges: Adam's telling her to keep moving forward, and secure the next cars, while he follows, prepping the train as they go. To Adam, "secure" means "eliminate opposition", including killing the crew. Blake was supposed to do that, and she had a crisis of conscience.
