Our protagonist D’Artagnan most frequently turns to the older and wiser Athos for guidance. His shrewd intellect understands how to exploit every advantage. For example, when D’Artagnan wants to burn the carte blanche, Athos points out it may come in handy. At the bastion St. Gervais, Athos alone of the four friends recognizes that the corpses at the bastion will be useful. And lastly, Athos is the first of the three that D’Artagnan seeks out when trying to dispose of his commission. After offering the commission to Porthos and Aramis, D’Artagnan returns to Athos in confusion. It is Athos that writes D’Artagnan’s name on the commission and consoles him when he gets upset at the idea of losing his friends.
Tréville serves as a surrogate father to all his Musketeers, but he demonstrates special favoritism to Athos, Aramis, and Porthos, who are particularly exceptional Musketeers. As a fellow Gascon, he mentors D’Artagnan and becomes increasingly impressed with his devotion, bravery, and skill. In the beginning of the novel, his role as confidante and mentor is especially strong, but it decreases over time, which marks D’Artagnan’s growing maturity and independence.
