Upon entering West Ardougne during Plague City, he is the first NPC you must speak to regarding Elena's absence. In order to gain information on her whereabouts, you must then show him Elena's Picture. He then gives you a book which you must return to Ted Rehnison.
Jethick, like most of the West Ardougne population, shows strong disapproval of King Tyras, believing him to be the cause of the plague. In the Song of the Elves, he is part of the Resistance and suggests riling up citizens by telling them that taxes are being increased.
