It was all intentional...her suicide that was. Sevestapol didn’t intend to only destroy herself. She wanted to at the very least try and take the gunslinger with her, but she didn’t have the strength to do it. But it was all apart of the plan. The plan to allow the Drifter to finally put that knowledge he got to good use... Right before she took her own life, she had grinned to herself, muttering something in a split second to the point where the one who did her in couldn’t hear nor see it being said. But someone else DID hear it...in the back of their mind. “This isn’t over...it’s only starting.”
