Loophole Abuse: 1987 Krang uses Kraang Sub-Prime's desire to kill the Turtles as license to destroy the entire Multiverse.

Let's You and Him Fight: The 2012 and the 87 Turtles fight briefly when they meet although the 87 Turtles were specifically trying to get the 2012 Turtles' help, 2012 Raph immediately assumes the device 87 Donnie had was a weapon.

This equals to twenty-two minutes total, which is the length of the total episode.

Leaning on the Fourth Wall: Thirteen minutes into the episode, the Donnies tell the other Turtles there are only nine minutes left before all the bombs are set to go off.

Hurting Hero: Modern Leonardo again shows that he's fully aware of the burden he's carrying, and Splinter easily senses something is wrong with him.

Raphael (using sign language: 'Will you fine gentlemen kindly wait here? And please remain silent, or I will strike you repeatedly in the face and bodily regions.' these particular 80s animated Turtles and the Nick Turtles are free to have their 'first meeting' while their counterparts had one where things went differently. note Their own view is that since the Multiverse contains so many alternate timelines and parallel realities, there's no need to disown Turtles Forever or tie into it. Although it could theoretically take place before Turtles Forever from the perspective of the 1987 Turtles. There are, however, some plot similarities, particularly an attempt to destroy the Mirage comics universe in order to destroy all the others.

Canon Discontinuity: The events of Turtles Forever are not acknowledged here.

Also, the very end of the episode has the 1987 Turtles confront the same Kraathatrogon from The Manhattan Project, except this time, it plays out a little more and sees Tiger Claw slice his way out of the monster and meet the 1987 Turtles, beginning his journey back to Shredder.

The modern Turtles get to see Splinter again during a brief return to Earth.

They also clearly get along a lot easier than the others.

Birds of a Feather: Both 1987 Michelangelo and 2012 Mikey hit it off during their first meeting, rather than attack each other the way the other turtles do.
