Ten

Leader: The leader is motivated by the other characters (duh) but not the chorus. The leader is the leader of the chorus, and therefore what the chorus says does not motivate the leader. The leader seems to form their own opinion that is different from the chorus, but that also defends the chorus' lines, which in Oedipus, usually question the story and relate to the gods.
"Oedipus- son, dear child, who bore you?" - Chorus
"a trusty shepherd, if there ever was one."- Leader
The chorus asks about Oedipus' parents, and later the leader puts his input on the subject, lightly, commenting on his opinion of the shepherds. He likes to have his input in, that is apart from the chorus.
