LMAO 11 layers of multiverse-spinning tragedy is so accurate, but she's generally feeling more like her cheerful self so she won't get too much angst on him this time.

I think them fighting together could be great! She can either use her regular sick skills on criminals (which will be slightly dampened due to corruption so it makes sense that she'd need backup), or she can stun vampires temporarily (the older the vampire the less the effect lasts) so they can be killed.

My understanding is that the only cure for darkness touching is light when it comes back so no worries on the lack of healing, it wouldn't help anyway.
