Superman: You never knew how I felt about you. I didn't know... until you were gone.
Broken Pedestal: Enforced. The writers explained that they wanted Jimmy Olsen to be a member of the resistance and explicitly wanted it to be him who began throwing rocks at Superman, because they felt that nothing would better demonstrate Superman's fall from grace than losing the adoration of his biggest fan.
For Want of a Nail: Lois' death turns out to be a big nail. Jimmy explains that Superman was a split-second late when Intergang put a bomb in Lois Lane's car. Because of that Lois died and Superman decided to take a more proactive role in running the city.
Just Following Orders: Once Alt!Superman learns about Alt!Luthor's lies, Luthor tries to kill him with Kryptonite and hopes to convince the people that he was just being forced to play along with Superman's plans before having a chance to stop him.
Knight Templar: The episode takes place in a Mirror Universe where Lois Lane's death has turned Superman into a tyrant who cooperates with Lex Luthor. However, this version of Superman still isn't nearly as bad as JusticeLord Superman and can still be reasoned with. Lex was lying to him and purposely got rid of people that could have told him he wasn't doing good. When Lois shows Superman the truth he is very ticked.
"For too long, I fooled myself into thinking I was doing a simple clean up job; that if I did enough good, people would follow my example. I didn't realize it was a war and, suddenly, you were a casualty of that war."
