In english she says "forgive them my beloved...." when we defeat her

It seems like no matter the translation she thinks of her lover. Which leads me to a question: is her dragon lover dead? She never says something like "I can finally be with you."

Its certainly possible the dragon is still alive and was probably of high rank. Afterall, motions peace are usually set by those in higher rank/ lead by example.
