Fractally speaking...........from Aaron as micro to Achilles as macro:

Achilles' name can be analyzed as a combination of ἄχος (áchos) "distress, pain, sorrow, grief" and λαός (laós) "people, soldiers, nation", resulting in a proto-form *Akhí-lāu̯os "he who has the people distressed" or "he whose people have distress". The grief or distress of the people is a theme raised numerous times in the Iliad (and frequently by Achilles himself). Achilles' role as the hero of grief or distress forms an ironic juxtaposition with the conventional view of him as the hero of κλέος kléos ("glory", usually in war). Furthermore, laós has been construed by Gregory Nagy, following Leonard Palmer, to mean "a corps of soldiers", a muster. With this derivation, the name obtains a double meaning in the poem: when the hero is functioning rightly, his men bring distress to the enemy, but when wrongly, his men get the grief of war. The poem is in part about the misdirection of anger on the part of leadership.

And so, fractally speaking, the story/plot has Aaron having his Achilles injured.
