Rodney Skinner liked to think he was a brave man.
Sadly, he wasn't. He knew that.
So he kept quiet when Mina, Nemo and Jekyll praised him for his "selfless act of bravery" when he saved Tom.
He frowned after that. But he kept silent.
He had done a good deed, even if it nearly killed him.
Rodney Skinner hadn't intended to push the flame-thrower out of the way, so Tom could live; he hadn't intended to save his life. He had been running from the battle.
He was the kind who had many accidents.
He had tripped.
He was just lucky something good had come out of it.
