How did you get Bob to go so fast?

Bob is going slower than light. If he's far enough away, and the signal is fast enough, he can be going as slowly as you like.

If it doesn't matter that Bob is even moving, then it was a non-sequitur within a non-sequitur, since you had no reason to say Bob moved at all. The main non-sequitur is that the signal is FTL, seeing as I never implied on this thread that anyone could send an FTL signal to anyone else. Hence there remains no evident reason to disagree with me.
