Tread Perilously returns to the timey-wimey with a month they just had to call "Let's Do The Time Loop Again!" First up: an episode of Fringe known as "White Tulip."

When Olivia, Peter, and Walter are called to the scene of a train car filled with corpses, it soon becomes clear a former MIT professor may be to blame. Walter quickly discovers the scientist is trying to use time travel to seemingly save his fiancée who perished several months earlier. Walter has his own experience with grief leading to mad science. Will he be able to talk the other scientist down from his experiment before more people die?

Erik and Justin like Fringe and make no bones about it. But they also like to make fun of J.J. Abrams, so they quickly get into the weeds with that. Star John Noble quickly proves to be the episode MVP, but guest star Peter Weller gives him a run for his money. Justin determines the three premises of Fringe. He also recounts how he derailed his calculus class. Erik presents more thoughts on Ghostbusters: Frozen Empire. The pair question whether or not the episode's time loop is effective, the real issue with plotholes is explored, and the real Richard Dragon suddenly becomes important.
