He smiled after they smiled. It seemed that they were going to go somewhere. That was nice to hear. Though his head tilted to the left when the Doctor called him Angel Castiel. He was no longer an angel. He would not mention it though. If that is what the man wished to call him then he would have no problem. He had saved his life. Castiel figured he was entitled to any strange nicknames he desired.

He looked down at their hands when Rose moved to stand by him. His smile grew and he looked up. He listened to the Doctor speak. He really spoke quite enthusiastically. It was almost a challenge for him to keep up. Rose had said the man could talk, but this was not really what he was expecting. He had a hunch this wasn't even the worst part either.

Castiel glanced at Rose and then looked to the Doctor with a smile. "He is quite impressive though." That was probably not the answer that Rose was looking for, but Castiel was very easily impressed by this man. It was very strange.

He straightened up and moved away from Rose. He made his way to the Doctor to stand by the console. His eyes swept over it. "I believe you should pick for me, Doctor. I would like to also know about her." Yeah. He was referring to the TARDIS.
