Confrontation.

Henry has been battling with his other identity, an evil, demented soul, that is always trying to win control.

{A songfic and (I guess you could say) my interpretation for the song "Confrontation", from the musical Jekyll and Hyde. It includes lyrics from the song - in italics and in the all of the dialogue. There is also some reference in the text to song "Prologue" from the same musical. I take no credit for it.}
