Talk:Dr. Jekyll's Serums/@comment-25491743-20161017215112/@comment-7345267-20161019094718

his original serum turns him into Hyde for a period time. He then apparently makes that same serum more powerful (to split the two entirely).

The serum in "Strange Case" may not be the same as that original serum. It was meant to destroy Hyde/one's "evil" side, but the question is, would a more powerful version of his original serum do that, or did he need to create something new for that purpose?
