In The Strain: The Third Rail Setrakian and his little team of strigoi hunters are starting to slowly gel as a cohesive unit. Neither Vasiliy Fet or Eph Goodweather will be the best of friends or the president of the other’s fanclub but they are learning to work together. At the start of the episode, Fet is testing the UVC bulbs and the experiment goes up in flames. Eph recommends making the bulbs fluctuate like a strobe and when Vasiliy makes a joke in agreement the doctor gets angry. The exterminator explains that he likes the the strobe idea which calms Goodweather down.
