He would live

Xavier sat in his sitting room, surrounded by so much darkness he thought he could see his thoughts swirling around in the background. No, there was only one thought, that woman, Sabine. What did he do this evening? He knew he didn't do it because he felt sorry or responsible for Isabelle, why did he even tell her about the bomb?

Giselle would figure it out, and it would be sooner rather than later. Was it because like Giselle only Isabelle knew the true identity of his first love? Why did he even think she would tell him? Those two hated each other so much yet there were alike in the sickest ways. That wasn't the reason he saved her though, he went over to that woman by himself and told her what Giselle was planning. And she told him to stop it and he did.
