I think that's actually what did happen. She fought off the illness (or possession) until she saw that Chaz had hooked up with Rune, then she died rather than succumb to the evil.
I don't think Alys was possessed or had an illness she was fighting. She didn't get sick until she was hit by the Black Energy Wave and that was before she could know for sure that Chaz would actually hook up with Rune. Also the BEW was aimed at Chaz, not herself, so DF targeting Alys to trigger something in her seems implausible to me as well. Why she has "Death", I don't know, it actually never made any sense but I doubt it was the creator's intent to make her somehow possessed.
