When Percy Jackson, Annabeth Chase, and Tyson the Cyclops arrived on the Princess Andromeda, they hear Luke Castellan down the hall, but can't make out what he is saying. Tyson on the other hand can hear them and unknowingly mimics Luke's voice, as well as the person he was talking with. Annabeth finds this to be very unsettling and tells Tyson to stop, but when he does he shows no signs of knowing what he was doing. When Percy tells him to keep going, Tyson once again copies their voices, only for the group to quickly realize that Luke had found out they were listening in.
