We all know that Lilith found Warlow's blood delicious, so it would only be logical to assume that she had a bite or two out of him even after he was turned. That should mean that she acquired daywalking abilties. However, considering that Warlow ultimately killed her by exposing her to the Sun, I think this ability wore off after some time.
We already know that vampire blood wears off humans after some time, and fae blood wears off vampires after a while. Could it be possible that hybrid blood might also wear off all the current daywalking vampires after the "time-jump" that Brian Buckner spoke about happens?
