And it's not like fate and destiny is his main laws and rules that he practices.
It is only because he is connected to the World Tree
He felt this feeling the last time.
In that other timeline.
Though the memory of that other timeline become more blurry as the past and present changed from the original storyline, Odin still managed to imprint some powerful emotions and send it back to this timeline
That other timeline no longer existed.
It is like a dream.
It never existed in the first place because of Jean interference
He always wondered how did Jean managed to change every single Time in every single Universe, affecting the entire Omniverse
If Jean was that strong, couldn't he delay the Destroyer?
What if….what if that being in the river helped him?
If that being in the river helped him, then it would make sense that Jean could do what he did.
