Freddy would most definitely doing his best to preserve his secret identity. He will make note of the storm activities including the fact that per the timeline it appears the storm began to manifest and draw closer when the first explosion occurred. Helps with his hypothesis.
As for Callaghan Freddy would be curious about the chief’s behavior given the fact that he’s surrounded and engaging not one metahuman but three from government agency. That along with the way emergency services and the general populace behave when their near him would make Freddy wonder if there is something going on. That and Callaghan’s resistant to the story that everyone’s buying from the government. He would definitely play his cards right to get in the Chief’s good graces and lean on Solomon to glean anything about Chief he can and the broach if he gets a look at the contents.
Nothing’s as it seems in Fawcett lately why not the Chief?
Also I may have missed it, but how is N.O.W.H.E.R.E identifying itself just as a government agency that deals in metahuman affairs or do they officially go by N.O.W.H.E.R.E?
