It seems that Manrico was faced with a Biowarian choice during the duel.
Back to Il Trovatore:

I also began to see the pattern. The whole genre relies on dramatic irony :stating the obvious:. That I realise more than the character does, is supposed to feel the impact of tragedy - which is bound to happen, right? At the end of it all I'd be surprised if it didn't come down to Azucena dancing on the ashes of the count and her own "son".
