Even if Arren was awake, he might not have had time to process the fact that he met one of the main characters because his entire focus would be on his Mister Investigator's true identity. Unfortunately, he was sleeping and thus missed the knowledge that he had unknowingly met two of the people he had avoided meeting his entire life and even flirted with one of them. Arren had a habit of falling asleep during crucial moments.
Spade nodded and said nothing more. He turned around and resumed his walk toward the elevator. His steps were swift but light, and his grip on Arren was firm. Many of his bodyguards dispersed, closely inspecting their surroundings.
He was aware that his leaving the palace would be discovered sooner, and that those with keener noses would have more information, such as his meeting an omega. It was only a matter of time, but Arren's identity would be kept hidden until Spade himself exposed him.
