And Orange has to survive long enough for the device to charge up, use a night action to activate it, and hope that it lands on a player who he can actually kill with it.
Also, I don't think anyone was seriously scum hunting until day three, Louis grabbed the device twice giving it an entire two phases worth of charge, no one role blocked him the night he was going to activate the device, and Sunflower was dead so she couldn't try to do anything with the bomb, and iLTS has lost his BP, Jeod didn't get passed the bomb either for his day BP. Not to mention, he wasn't day killed by Retaliation or blocked by KY before he could activate his shield to defend himself. Oh yeah, and he didn't get NK'd before he could use the proper night action either.
There was a good list of things that could have gone wrong for him.
