“You bled so much for me. These are wounds from the hundred man battle, right? Even the wound I gave you…”

“I too want a wound… that I can say you gave me.”

When it comes to Guts’ guilt issues surrounding Griffith’s tragic narrative, and the highly sexually charged nature of the scene where the Beast of Darkness suggests this, and the fact that the Guts and Casca sex scene is already chock full of references and parallels to Griffith, I’m feeling like this is a legit comparison, at least from Guts’ guilt-ridden and Griffith-obsessed point of view.
