can i get the insight of someone who has read/is familiar with the iliad? i know that neoptolemus is also called pyrrhus but i don't know the full context of his two names or whether its implied he has any feelings or preferences surrounding them and i often go back and forth with what to call him in fics and stuff, so i was wondering if there's anything in canon to go off of. i'd love to have a little flynn rider/eugene fitzherbert moment where he goes by one name but is more comfortable with another and opens up to telemachus when he trusts him, but it would also be fun to play with other ideas. i've seen a couple different interpretations in fic so i'd just like to get some more info!
