Answer:
He murdered someone.
Explanation:
In The Odyssey, we meet Theoclymenus. He tells us that he lives in exile because he killed a man, and the man's relatives are looking for him in order to avenge the death. Telemachus is inclined to be kind and helpful to Theoclymenus, as he is a seer and Telemachus might be able to benefit from his psychic abilities.
