If he was being honest, Aiden had no reason to straighten the misunderstanding that had happened between Anna and Agnas.
It wasn't his place to do anything.
In the first place, Agnas was dead and Anna's bitterness has just gone cold over the years. He could tell by seeing how she was living.
But then, why was he doing that when he should try to promote [Agnas] more and prepare for the clash against [Judgment] next week.
He didn't know the exact reason but maybe he had to point out something — It would be the connection he felt with Agnas like he was a part of him, more than his other characters.
Using 'Connect' was almost like living another life and Aiden still had the emotions that Agnas had felt in his life inside of him somewhere.
When he had first known about Anna, there was a feeling of agony and torment inside of him.
He felt like Agnas was still alive in him and he needed to give peace to that part.
