Seeing Luna like that was painful to say the least. In the past, Uriel wouldn't have hesitated to give her a hug, even while he was under Water warlock's influence. Just because he didn't experience emotions it didn't mean he couldn't tell what was the right thing to do. Now, however, things were different.
They were in a dire situation and their time was running out. That's why, instead of giving her the comfort Luna desperately needed, he decided to talk sense into her by using logic and reason.
"Luna, I know exactly how you feel, I'm quite overwhelmed right now, but this isn't the time to be overwhelmed. You say Medusa left with the Mapple corporation, it's unlikely, but even if that's the truth then at least she's safe. We aren't," Uriel spoke calmly looking her directly in the eye and the continued. "I think I know what's going on, but I need your help to figure things out."
