This is something that makes the show very different from others: the leader of these True Companions is not the choleric character, but the melancholic one! True, Sarah Jane is still a little bit choleric at times (coz she's their leader) but she's quiet and independent, and completely occupied with all that's wrong in the world. Not to mention the shedload of melancholic moods she goes through due to all the stuff that happens to her in each series (do the writers hate her?). Effectively making this team leader the woobie.
