Suppose Thor really never got to say goodbye. The few words of you remaining and lurking upon his mind. Your death laying in his heart--a tragic death upon the war. Ever since,he changed his personality. His loyalty remained only to you--his dead lover. He started acting cold towards everyone and anyone. Even his own father--Odin.

Upon seeing you on the other side of the arena,his eyes widened. You,his lover,was his own opponent for this rank of Ragnarok.
