I half expect the announcer/broadcaster girl to be the thief, to tie the two plots together. I feel like currently their feud shown here isn't really on equal footing (with the broadcaster just having stooped to "frivolous" news, while the newspaper girl actively harms peoples' reputations with gossip), so with a reveal that the phantom thief was actually the broadcaster (in my assumption, posing as a phantom thief as a way to generate hot news to drive viewership) it would put them both in the camp of "doing things that are actually kinda bad and they should stop".
Plus, it would make her complaint about Freed's mask here kind of a slight jokey hint, with her being someone who's very knowledgeable/opinionated about good disguises.
