Gregory can't believe that he is now holding his child in his arms. Mary is still unconscious but she's already away from harm. He is now enjoying his first moments as a father. After living for over 500 years, he never thought that it would even be possible.
Thanks to his wife, he can now feel how it is to be a father. Their son looks like him but he got Mary's brown eyes. It's amazing how a vampire can have a child. But miraculously, they did and he can't get over the fact that his son is a powerful vampire.
He was able to save his mother from a rogue angel. Although Mary has no idea yet about what happened. But Greg can't forget how Mary did that to him. She allowed another guy to kiss her! He doesn't know if he can ever forgive her for that.
"That baby looks like you!" Angel commented.
