When you watch Grimm Season 5 Episode 15 online, a professional photographer approaches a young woman in the mall, compliments her beauty, and asks her to come down to his studio so he can take photographs of her because she obviously has a future in modeling. Though everything seems to be going well at first, she falls victim to drugged water and passes out. The man is revealed to be a horrifying-looking Wesen. She wakes up none the wiser for her assault and goes home, only to drop dead the next day... of old age. The photographer, meanwhile, sells the extract of youth he stole from her to an incredibly unethical doctor, who is also using it on himself despite the photographer's repeated and vehement warnings. As Nick and Hank investigate, it's up to them to figure out what happened and stop this duo before more innocent victims pay with their lives. Meanwhile, Renard ponders whether to run for mayor, and Eve warns Nick and Hank about Renard's possible involvement, knowing or not, with Black Claw and the assassination of Andrew Dixon.
