First, Athos needs to realize the full extent of the hurt he has caused. He should approach Aramis sincerely and apologize. For example, he could say 'Aramis, I was wrong. My words were thoughtless and I deeply regret hurting you.' This simple act of acknowledgment can be a first step towards healing the relationship.
Athos could also make an effort to show his support for Aramis in a public way. For instance, if there is a mission, he could specifically request Aramis to be part of it and praise his skills during the mission. This would help boost Aramis' confidence and show that Athos truly values him. It would also signal to Aramis that Athos is trying to make amends for his previous mistake.
One possible scenario could be that Athos made a critical comment about Aramis' skills in combat. For example, he might have said something like 'Your swordplay lacks the necessary precision lately, Aramis.' This could really hurt Aramis as he takes pride in his combat abilities. It could lead to a rift between them, with Aramis feeling betrayed by his friend's lack of support and confidence in him.
Aramis could choose to confront Athos directly. He might say something like 'Athos, what you did really hurt me. I don't understand why you would say such things.' This way, he gives Athos a chance to explain himself and they can start to resolve the issue.
Maybe Athos is jealous of Aramis. For example, if Aramis gets more attention from a certain person they both care about, like a mutual friend or a love interest. This jealousy could lead him to say or do things that unintentionally or even intentionally hurt Aramis's feelings.

Show his actions. Maybe Aramis withdraws from social situations. He stops going to his favorite places or stops talking to the people he used to be close to. This shows that his feelings are so hurt that he wants to be alone.
First, they would need to have an honest conversation. Hermione would have to admit what she did wrong and why. Harry, being the forgiving person he is, might be able to start to understand her motives, even if he doesn't agree with them right away.
