Rose and Lissa's bond will eventually come back.
Someone will find a way for Damphirs to have children together
Someone will charm wards with Spirit.
Victor caused the infamous car accident.He knew about the bond before anyone else. Maybe not just because of the crow thing either. If he didn't already know, why would he have had Natalie follow them?
The Shadow-kissed are (somewhat) immortal.In the Shadow Kiss graphic novel Victor says to Rose "All things die, Rose! Except maybe you!" Now, this might of just been Victor being Victor, if it wasnt for the fact that every single Shadow Kissed character mentioned is either alive (Rose, Jill, Mark and Averys brother ant guardian) or dead (Anna, Alden(Roberts bond mate)) but have died in some unnatural way, like suicide or in a strigoi fight. So my theory is that the Shadow Kissed can live forever, as long as they manage to stay well away from danger, and are unable to die in natural ways, like heart attack, stroke or old age.
