Since he teloprted one of the villains why would he tell his girlfriend to drive home when he could pause time, teleport her back home and return to the scene since his main priority was saving her? Her death plot was too stupid. Saw the future twice, one was when his future self told him what will happen and second was at the finale and Michael and the writers of the show blew it.
The show is nice, I enjoyed watching it since Netflix doesn't have anything worthy of late but the writers could do better. That finale was BS
