ST:TNG:23 - "Symbiosis" (Stardate: Unknown) - this is the 23rd episode produced but the 22nd episode to air on TV - it was proper that it aired before the 22nd episode because of what happened in that episode "Skin of Evil". Though I won't give away why, let's just say a familiar face returns here that supposedly died in the 22nd episode. Another familiar face to appear here is that of Merritt Butrick as T'Jon - he was David, the son of James T. Kirk in the Star Trek movies II: The Wrath of Khan and III: The Search For Spock. The subject matter is also very interesting because it deals with narcotics and drug use - about how one race "enslaves" another by using a narcotic to control them - we get to see what drug withdrawal does to them (scary to say the least).
