Risa

Risa was one of the Future Dean's followers in the post-Apocalyptic future that Zachariah sent the Present Day Dean to. Not much is known about her past, but she and the Future Dean were implied to be lovers of sorts. When she learned that he had slept with another woman one night, she angrily confronted him - not knowing she was actually talking to the Present Day Dean.

Later in the episode, she participated in the attack on Lucifer. Future Dean sent her, Future Castiel, Future Chuck, and some others into a building, despite knowing that it was a trap. She was likely killed along with the others.

Her current status is unknown given that the Winchesters managed to avert this future.
