I just thought she was in another area for a better angle on the Mc bowling, also for the ones at the station, I believe reporters have sources inside that could have tipped them off or be connected to a scanner, I don't believe it is Bella for two reasons Rachel vouches for her and I didn't get the feeling throughout the conversation that this would be in her nature, Katie though, that is another story, she hasn't looked trustworthy from the beginning with the invading Charlie's office and trying to bang the MC out of nowhere, and being there coincidentally at the same time as a drugged-up Charles, and then disappearing with him and never contacting her brother.
