This was fabulous, you finally posted it! You did your best to prevent Penny from dying, and you also know about the queen's plan or something like that.
In the next chapter, Master Splinter will also be involved; he will do something to prevent Yang from losing his arm in the previous battle with Shredder.
Here's an interesting fact: Donatello, with Ultron technology, could hack to remove the virus's manipulation and also restore communication, thus preventing much death in history.
Regarding the silver eye, instead of Pyrrha dying, it would be Penny who would be destroyed by Cinder. I would activate her eye and attack her, but Penny could be saved thanks to Donatello, who can rebuild her.
And making it much better with Ultron technology would be much more advanced.
