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.
I'm not sure specifically as there's not much information given just from 'athos is short fanfic'. It could be a short fanfic related to a character or story named Athos. Maybe it's about the adventures of Athos in a fictional world created by the fanfic writer.

The 'pvz back story' is mainly about the war between plants and zombies. The zombies are attacking the plants' territory, and the plants have to defend their land. Each plant has its unique ability to fight against different types of zombies.

One idea could be a story where Athos, Porthos, and Aramis go on a secret mission together. They face many challenges and have to use their unique skills to overcome them. For example, Athos' calm leadership, Porthos' strength, and Aramis' charm and intelligence all play a part in the success of the mission.
Well, the theme of second chances is quite common. It gives the idea that Milady could have a new start, especially in relation to Athos. Also, the theme of secrets and revelations.

Either Athos or Milady might sacrifice something for the other, be it their reputation or their own desires.
One popular Athos fanfic might be those that explore his backstory in greater detail. For example, stories that focus on his early days as a musketeer, his training, and how he developed his skills and honor code.
