Lola was a villainess from "Blade Runners," episode 9.16 of Supernatural.
She was played by Rebecca Marshall, who later appeared as the evil Captain Matthews in 12 Rounds 3: Lockdown.
Lola was a demon who was shown in the beginning of the episode engaging in a sexual encounter with Crowley, while also enabling his addiction to intravenously served human blood (which began with the trials in the Season Eight finale). Shortly after her tryst, Lola was revealed as an informant for Abaddon, a Knight of Hell and Crowley's rival for Hell's throne. The villainess was shown reporting to Aldo, one of Abaddon's minions, about Crowley; stating that he's in no shape to combat against Abaddon. Among other information, the evil Lola also informed Aldo about Crowley being in contact with the Winchesters, and mentioned that they were searching for the First Blade (the only weapon powerful enough to kill Abaddon).
Later in the episode, Lola returned to Crowley after a shopping spree and was set to give him his latest dose of human blood. At that moment, Crowley later tossed Lola towards the bedroom and confronted her, as he had known about Lola's double dealings. After denying the claims at first, Lola berated Crowley and mocked him and his current state, which led to Crowley killing the duplicitous villainess with an angel blade.
