WARNING: The following contains spoilers for Teenage Mutant Ninja Turtles: Jennika II #4 by Ronda Pattison, Jodi Nishijima, and Shawn Lee, on sale now.

In the world of the Teenage Mutant Ninja Turtles, life in Mutant Town isn't easy for anyone, least of all the Splinter Clan who have been trying to protect their city from all manner of threats, only to have more thrust upon them in the form of a dire warning from the future.

Jennika has been having an especially difficult time of things between keeping Mutant Town's reputation with the outside world in check, and discovering that she is seemingly the sole reason the Turtles are staring down such a dark future in the first place doesn't help. As hard as she has tried to escape her violent past, nothing Jenn does can keep her from being her own worst nightmare, as she just realized in Teenage Mutant Ninja Turtles: Jennika II.

Lita, the white turtle mutant that the Splinter Clan has taken in, returns from decades in the future, all grown up and shaken to her core. After explaining how she came into possession of the scepter which let her travel back, she tells the Turtles that she's come back to try and prevent the horrific future she's lived through. Jennika is outraged by the mere thought that she could still be that kind of cold-blooded killer somewhere inside herself, but that outrage comes from a place of fear more so than anywhere else. Her worries run so deep, in fact, that all she can dream about at night are the bodies of her friends piled on top of one another after being slaughtered by her very own hand.

Jennika wakes up screaming in a cold sweat from the nightmare, young Lita's face just below Jenn's blades burned into her mind. Unable to rest, Jennika goes out for a late patrol and comes across a well-dressed mutant banging her fists against one of the Mutant Town gates, demanding to be let out. The woman recognizes Jennika as a Ninja Turtle, but isn't sure exactly who she is. When asked what is so important to her on the other side, the woman replies that she has been separated from her son. Jennika brings her to the community center so they can talk, learning that the woman's husband was a mob boss before he was killed. Not only is Jennika's new acquaintance embroiled in the world of organized crime, but her situation hits too close for comfort once she realizes that she was the one who took the man's life.

Before she became one of the Turtles through a lifesaving blood transfusion, Jennika was one of the Shredder's most favored lieutenants among the Foot Clan's ranks. Jennika spent nearly her entire life after escaping prison as part of the Foot, her devotion bordering on fanatical at times. It was only after Splinter killed Shredder, claimed dominion over the Foot Clan, and defeated Jennika in combat that she even began to come around to any point of view other than one framed in absolute violence. Splinter's teachings and her time with the Turtles and their allies have given her a second chance at life, one where she can protect and build instead of destroying.

Now, Jennika is in the untenable position of being haunted by that old life while also looking forward to reliving it, with no way of knowing how to save herself.
