Re: During the procedure.
Godric isn't a healer. That's his brother Geoffrey. But what he is, is good with magic, and although his knowledge of dark magic is squat compared to what it will be later on in life, it's not like he's wholly unfamiliar with the subject either. He's in a rare mood of seriousness as he does his part to help - partly because he'd feel badly if he messed up and hurt Draco accidentally, partly because he's a little too fascinated by the entire project to not pay full attention.
