Sloan & Trask

I know that Tina Huang knew about the war weapon that Dimitri tried to activate, because it was in her script, the one that she had taped & blocked with Serfati, but where’s the story of the “character” of Melinda Trask knowing of it? Is she in any position to get Dimitri into a Federal Prison, much less solitary for that matter, given that Dimitri & Megan had gotten immunity for those crimes, explain as to why Melinda doesn’t know that?
