These two unnamed angels briefly abducted Kaia Nieves.
History
In an attempt to capture Jack, these two angels pose as an ordinary man and woman and trick Kaia Nieves, a woman being pursued by Jack, into their car. Once Kaia gets inside, the female angel knocks her out and the angels drive off to another location.
They hold Kaia hostage. When Kaia asks why they abducted her, the angels explain their intention to use her as bait to lure Jack to them, whom they reveal is also the son of Lucifer. Kaia doubts Jack will actually come since she had run away from him earlier.
Jack does come as expected, along with Sam and Dean Winchester, much to Kaia's surprise.
