- Remake Cameo: Guest star Dean Cain, who plays Dr. Curtis Knox, previously played Clark Kent/Superman in Lois & Clark.
- Sins of Our Fathers: J'onn maintains that Kara cannot be trusted because her father, Zor-El, attempted to murder Jor-El back on Krypton.J'onn: Your cousin's arrival cannot be taken lightly, Kal-El.
Clark: I went to see my father. He gave me the same warning. But I don't get it; she's my cousin, the only Kryptonian family I've got besides a disembodied voice from the arctic.
J'onn: And she could use your longing for family against you. She's dangerous. Her father tried to assassinate Jor-El.
Clark: They were brothers.
John Jones: Their hatred for one another was stronger than any familial bond. Does Kara have her crystal?
Clark: Not anymore. It was in her ship when it exploded, but now it's missing. I've been trying to help her find it, but we've had no luck.
J'onn: If she gets to that crystal, everything you hold dear in this world could be lost. You must find the crystal before Kara. Trust is a luxury you cannot afford. - Villain of the Week: Dr. Curtis Knox, an immortal Deadly Doctor.
- What Happened to the Mouse?: Knox's fate after his fight with Clark is uncertain. What is known is that J'onn did something to make sure Knox doesn't hurt anyone else, and he tells Clark it's best they have a "don't ask, don't tell" arrangement when it comes to dealing with criminals.Clark: What'd you do with Knox?
J'onn: Your father and I had a "don't ask, don't tell" policy when it came to crime and punishment. I suggest we abide by the same rules. - Who Wants to Live Forever?: Knox gives this kind of speech to Clark during their fight.Clark: I won't let you kill anyone else.
Knox: I'd kill one thousand more to never have to be alone. You don't know the pain of living centuries, watching the women you love grow old and turn to dust! You and I are more alike than you think. I won't go through that again!
