Jenna Nickerson

Jenna Nickerson is a sheriff's deputy in Superior, Nebraska.

Background
Jenna started working as a deputy three weeks before the darkness was released. She was also good friends with Mike Schneider.

Season 11
She first appears in Out of the Darkness, Into the Fire when she shoots a creature infected by the darkness who was approaching Sam and Dean Winchester. She reveals that she was injured, and the Winchesters use a wheelchair from the trunk of the impala (which was most likely used by Bobby Singer) to help her into the nearest hospital where Dean stitches up her wound.

When Sam rejoins them, he is followed by Mike and his baby. Sam then finds out that Mike had been infected and Jenna tells them that she believes he should be allowed to remove himself from the group before he turns fully into a monster. Mike agrees, knowing that the creatures eventually die of an unknown cause after a certain period of time. He entrusts Jenna with the baby as he says goodbye.

When Castiel calls Sam and Dean, she comes to the realization that they are not FBI agents and they confess to lying. Sam then decides to use himself as bait to distract the monsters who are rapidly closing in, and Jenna and Dean escape with the baby. They are stopped by Mike who seems as though he wants the baby but only wants to tell them that her name is Amara.

Later when Jenna is changing Amara, she notices the symbol of the Mark of Cain on her chest, revealing that Amara is the darkness in the form of a baby girl.
