Sam Trueheart / True of Heart

True of Heart was the native American guide who assisted young Tommy on his Zeo quest, and supplied him with half an arrowhead, the key to his family secret.

Back in the present day, teen Tommy met Sam Trueheart, who looked just like the man he met before. He led him to the desert where he sent Tommy on a Spirit Quest, which led him to his long-lost brother, David.
