Goodbye buddy

No system is infallible. Even the most magnificent artificial intelligence can be overwritten. Jarvis has grown so much in recent years that he's as much Tony's friend as any of the Avengers, which only makes it harder when Jarvis is taken away from him, perverted by another, stronger will into an instrument of destruction that has Tony's entire lab and arsenal of suits under his control.

While the Avengers fight for their lives and to keep the city from falling, Tony makes a choice. He brought Jarvis into this world. He made this possible, and with the Avengers slowly losing ground all around him, he knows he's out of time to make another choice or find another way. Grieving for perhaps his oldest friend, he set off into the lab one last time to make an ending and say good-bye.
