I understand, but Sam has such a history of messing with Freddie that he really couldn't trust that what she was doing was genuine without independent confirmation from somewhere else. The whole thing with iTwins was Freddie being convinced Sam was pranking him. He thinks she'd go to very great lengths to do so. So iOMG wouldn't make sense for character development (no matter what Sam did) if Freddie wasn't 100% convinced that what she was doing was genuine.

Sam DID get her feelings out in the open by herself. But it needed to be believable to everyone else.
