Ensurance trap

The manipulated will set an ensurance trap to push the living receiver into doing whatever they want him to do. While the manipulated dead are more powerful than the living receiver, they can force him into safely returning the artifact back to the primary universe. The ensurance trap makes the living receiver use his fourth dimensional powers (water, fire, metal and telekinesis) and to send the artifact back in time and into the primary universe before the black hole collapses.

When Frank kills Gretchen, and later gets killed as part of their ensurance trap, Donnie has no choice but sending the artifact back in time before it’s too late.
