IDW Renet and Mirage Renet are actually one and the same character shared by both continuities&mdash;IDW was given permission to directly use Mirage Renet in its stories. The same goes for Savanti Romero and Miyamoto Usagi, which are the same characters in the Mirage and IDW continuities. The IDW continuity is actually a parallel timeline from Mirage, and represents the direct future of the Mirage time travel story The Return of Savanti Romero! as revealed in the IDW miniseries TMNT: Bebop & Rocksteady Destroy Everything!.

And IDW Renet did become romantically involved with Baltizar, who appeared in the Teenage Mutant Ninja Turtles 2014 Annual.
