Lots of twists, lots of new elaborations, lots of new connections.
In the original canon of the early 80's TMNT, we meet the Turtles and Splinter in issue 1, along with the Shredder and his Foot ninjas. In issue 2, we meet April O'Neill and Baxter Stockman, as well as the Mousers, and in issue 3 April is mistaken for a robber driving an identical van. Here, things are happening out of order, out of sequence, compared to the original canon, but - but - it's in the words of one of the two original creators of TMNT from the early 80's.
Call me a loser all you want - but then, what are you doing on this page, if you're so much better?
