Does Michael die in Warrior Nun Season 2?
Unfortunately, Yes! Michael has indeed died in the second season of the Warrior Nun. He died at the hands of Lillith, who was blinded by her newfound powers and was under the influence of Adriel.
When Michael was wandering in the deserts in Adriel’s realm, he was encountered by some wandering angels, who took him to Reya. There, he was trained by her to fight Adriel.
After returning to Earth, Michael knew that only he and Warrior Nun could defeat Adriel, so he sought Ava. However, beating Adriel was challenging; after making plenty of attempts, they couldn’t succeed. So, one day, Michael told Ava that Reya had sent a Divinium bomb that could be used to kill the demon. After that, Ava gets surprised to see that Michael has the bomb inside his body.
In episode 8 of Warrior Nun Season 2, Ava and Michael meet Adriel in the basement, and when the latter tries to get near him, he is stabbed by Lilith from behind in a brutal fashion. Lilith takes out Michael’s heart from his body and kills him. On top of that, Ava directs the power of Halo into Michael’s lifeless body to trigger the Divinium bomb, thus destroying his body. Hence, yes, Jillian lost her son again, this time forever.
