This episode provides examples of
- Berserk Button: Messing with Leo's friends and families. Kojima presses it so hard that it leads to his defeat.
- Big Brother Instinct: "No! You leave my friends and my family ALONE!"
- The Chains of Commanding: See Deconstruction.
- Continuity Nod: Lord Hebi makes a brief appearance in Kojima's scroll, ordering the assassination of Usagi, Gen and Leo. This is a nod to the season 3 episode "The Real World Part 1" where Leo goes to Usagi's world and battles Hebi with Usagi and Gen
- Deconstruction: A minor one occurs when Mikeyyes, Mikeypulls off an accurate analysis as to why Leo takes the burden on being the leader: so that he lets his brothers be themselves.Mikey: I think you all [Donatello, Raphael and Casey] should just lay off the poor guy [Leonardo]. I mean, it can't be fun always being the responsible one. And we're the ones who really benefit: Raph's free not to think cause Leo does all the thinking for him, Don's free to dream, and I'm free to take it easy all because Leo's busy being responsible enough for all of us.
- The End... Or Is It?: While Kojima is defeated and everyone's safe, Splinter and Usagi acknowledge that Leo's anger issues are only going to get worse.
- My Greatest Failure: While sparring, Leonardo laments his failures in "Exodus Part 2" and Usagi responds with one of his own.Usagi: My own master was cut down in battle... right by my side. It was my duty to protect him. I, too, failed.
Leonardo: Usagi, I'm sorry. I didn't know.
Usagi: Failure, fear—in the lives we lead, these things are inevitable. How we deal with them, that is the true test of our character.
- Mythology Gag/Continuity Cameo: Gen, an anthro rhino, is impressed by a New Yorker's outfit and gets his own set. He ends up looking like Rocksteady. In addition, Kojima the assassin is a boar, a possible nod to Bebop.
- Narrator: Usagi's first time
- Race Lift: A (possibly unintentional) in-universe example can be found here when Michelangelo shows Gen a comic book issue about the Silver Sentry, and on the cover, Silver Sentry appears white, though the actual Silver Sentry we see in the series is black.
- The Reveal: Usagi and Gen's visit was Splinter's idea, hoping that Usagi will help talk some sense into Leo.
- Roaring Rampage of Revenge: Hebi has hired Kojima to kill Leo, Usagi, and Gen in response to them foiling his scheme in "The Real World Part 1."
- Shadow Archetype: Leonardo is this to Usagi. Both suffered major defeats, but Usagi was able to deal with in. Leonardo can't and is headed down a dark path, which Usagi doesn't want to see happen.
- Sssssnaketalk: Hebi speaks this way in Kojima's scroll.
- Temporary Blindness: Leo is temporarily blinded when Kojima throws powder in his eyes.
- Villainous Breakdown: Kojima remains quite confident for most of the battle, but after getting smacked around by Leo and seeing all the heroes about to gang up on him, he loses his cool.
- Worthy Opponent: Kojima congratulates Usagi for the fight he's put up. Before trying to deliver the final blow, he promises to remember him."Take comfort in that."
