Jason & Marion
From the very moment that Jason had told him that not only he had a son, but the mother had been murdered, and he'd be moving in with his father now, Cat had a feeling that things weren't simply cut and dry. She hadn't said anything, though. She had no reason to voice a gut feeling without any proof to back it up. Mainly because it hadn't been her place to say anything without proof. With Morgan being kidnapped, now she wished that she had followed her gut and looked into things sooner. Not that she even would have known where to start.
She couldn't let the guilt get to her now, though. She was on a mission, and she would do anything for her King. Going in the front door wasn't exactly something that she was used to on her normal missions. It was usually about finding the least conspicuous way of sneaking in, but she wasn't about to questions things now. Now in full "Marion" mode, she gave Arthur a nod once she was ready and turned her earpiece on. "Let's do this," she said softly, trying her best to not smile, despite it being quite normal for her to do so at any time.
