The pinching had hurt, therefore he wasn't dreaming. This had to be a joke. The work of a shapeshifting Servant? Did they have one of those with a high Self-Modification skill? His grogginess wasn't helping him to think clearly. "H-How-- It shouldn't be possible," Roman pointed out plainly. Wait-- did he just say Heroic Spirit? He glanced over his shoulder and tapped a key to notice there was a Registered Saint Graph (well, two, but Chaldea had his hidden under lock) in the Control Room. His eyes widened. "T-That's impossible! How are you a Servant?!"

He was probably was confused as Waver was for the time being. Of course, there were explanations that immediately came after his fatigue made him overreact. One was that he was a Guardian, but such wasn't the case when he read the clear name of the registered Spirit. Roman sighed heavily. "Oh, you're an irregularity." A Heroic Spirit inhabiting a human vessel who wasn't a Ruler? That was new but, he could roll with it.

He waited until the awkwardness subsided to greet him.

"I apologize for the delay, but welcome to Chaldea," he said with a sheepish smile, "I'm sure you have many questions."
