Why Was the Orca Used on Mothra?
When Mothra hatches, we see her create all kinds of problems for the folks that are in the lab/area with her, & then we see Emma struggle to use the Orca for the correct frequency to tame her, but what I'm asking is why?
Traditionally Mothra has been a human friendly monster, so A: Why were they afraid & B: Why did she in turn attack? Granted we don't see Mothra interact with humans the rest of the movie but still I have to wonder what that was all about.
