Ronan appeared to be an ordinary human and very ordinary standing near Caduceus, but there was magic to Ronan because Ronan wasn't an ordinary human at all. He, in fact, wasn't human at all. Ronan was a dream as much as he was a dreamer himself. And that is why Ronan asked if he had made Caduceus. Caduceus looked like something Ronan would see in his dreams.
"What flowers are you planting?"
Ronan dropped into a crouch, not standing too far from Caduceus. He was inspecting Caduceus' work. "Nah, I don't need anyone brought back to life. I was just wondering if you were fucking around with the dead."
