Marco didn't really like the secrets happening right in front of them, either, but it didn't bother him as much as it bothered Juno, clearly. He jumped when she slammed down her milkshake, and quickly shot a look towards the carrier across the room, glad that the baby hadn't been woken up by the noise.
Still, he scooted out of the booth to let Juno out, since that was clearly what she wanted. Not that he could blame her. "Let me know if you need me?" he said softly to her as he moved. He raised an eyebrow at Oliver and Cecilia, hoping that they understood that they had done nothing for Juno's mood.
