Are the following assumptions about this thought experiment correct?...

If an interference pattern is detected the bomb is defective because there was never any possibility of a photon being observed and collapsing the wave function.

In the case that no interference pattern is detected and the photon arrives at the detector at the end of the interferometer a photonless beam of light must have traveled through a functional photon detector/bomb trigger. This means the bomb is not defective because the photon that wasn't actually on the path to set off the bomb somehow knew that it would be detected there and the wave function collapsed even thought the photon was on the other path.
