He hated those names,
but then again.
Maybe he needed to be the person behind both names. For everything that Whale had done, he was confident and skilled. And for all the misery that had come over Frankenstein, what Victor had accomplished with that name had changed the scientific view of his land and maybe even of worlds beyond his. Whale and Frankenstein were opposites on many levels, but that made that maybe, just maybe he could use both, be both. Balance the bad characteristics out. Be confident without being arrogant, driven without obsessed. Whale's arrogance could be neutralized by Frankenstein's uneasiness around people. Frankenstein's obsession with science and death could be ceased by Whale's privileged indifference. And maybe then could he be the better version, of the pathetic person he was, he had always wanted to be. Make him a better self.
Because honestly: he wasn't such a bad guy.
