Ralph didn't know where he was right now. It's like there's a red veil on his eyes. All he can see is red around his surroundings. The blood moon seems to hide from the clouds a little. He is suddenly able to think straight but then remembers what he did earlier. It's the worst part of being a vampire for him. Not being able to control himself even if he knows that he should not do it. Before he attacks, Arabelle has already left for the golden bridge.
He felt weak when he thought about the boat driver. It's not his fault that he can't control himself. Although he still feels like it's a burden to his conscience. That's why he goes to the forest before. At least in case he loses control, he can't hurt anyone. Although he sucked blood from wild animals, he didn't feel bothered. Yet, he still decided to go with Arabelle to help her out. Even if he knows something like this will happen along the way.
