It could be Gerard, Ms. Blake, Girl on bike, or it could possibly be Derek's love interest. The bite didn't kill Jackson, it turned him into a mythical creature. Gerard isn't dead, yet so it could be him turning him into that kind of mythical creature. Or it could be Derek's love interest, since she was bitten, but Derek killed her. But she still could be a possibility seeing your comment saying it could be someone from the dead. And it couls be the girl on the bike, or it couldn't seeing she was trying the help them.
