As you know, Rido has been under some sort of protection shield with Muraki's help and he's taken Aidou as a hostage so that he can slowly feed off of his blood. To keep Muraki out of trouble, he and Rido are using the excuse that he is being compelled by Rido so that he cannot be blamed for his actions during this fiasco. Thanks to Lelouch's hacking abilities, the teams have been given Rido's current location and they are able to probe him no, that wasn't intentional XD for updates if need be.
Kaname's team will get to Rido first. They will inform the others, who will soon follow. To cut down on an overflow of posts, it will be assumed that everyone on the three teams is a part of this, but the action for the main thread will be limited to the VK cast and Muraki. We thought it would be easiest to keep this as brief as possible so that characters are not tied up in this event any longer. But feel free to speak up if you think otherwise. :D
Meanwhile, Kaname gets to Rido first and they have a somewhat evil exchange before he slices him up into little pieces. We're giving Kaname the reigns because we wanted to think of a scenario where Nyte didn't have to lose Rido and, more importantly, his memories and CR. Because Kaname is in a binding situation with his uncle, he is unable to kill him. The best he can do is chop him up. It will require some time for his body to regenerate after he is reduced to smithereens and it will allow Sentience to form a rehabilitation plan.
Rido, knowing that his best chance of survival is for his nephew to take him down, will send Muraki after Zero. Rido also knows that Kaname would never allow Yuuki to have a face off with their uncle alone, and that he will, instead, deal with Rido by himself. As Kaname gets to Rido, Muraki will take out Zero with one of his spells so that he is paralyzed. He will either do this in front of everyone or be sneaky about it so that his powers aren't outed. We decided to do this, again, because we wanted Rido to have the opportunity to live. If Zero got a hold of him, dying was pretty much inevitable.
While this is going on, Yuuki will tend to Aidou, who has been ensnared by Rido's charm. After snapping him out of it, she will get him to safety and worry over Zero. Before Muraki releases Zero, the bots will come and take away Rido's remains and put them in the infirmary, where he will regenerate. Sentience will put a shock collar on him so that when he wakes up his behavior is monitored. He can speak to everyone and move about freely, but whenever he does something that displeases Sentience, he will receive a shock.
This should all happen within the next couple of days.
