Falcone (John Doman) decides to put an end to Cobblepot's (Robin Lord Taylor) debt to Maroni (David Zayas).
After receiving information from Nygma (Cory Michael Smith), Gordon (Ben McKenzie) and Bullock (Donal Logue) realize Crane created the toxin after his wife's death, hoping that people use it to overcome their deepest fears.
He's then joined by Alfred (Sean Pertwee), who tells him that he came looking for him, but decided to let him crawl the last hundred yards up the hill on his own, to let Bruce develop his independence.
In the hospital, Gordon is notified by the doctor that because of the high levels of toxins, Jonathan (while he will live) will forever be forced to see his fears permanently.
The episode received a rating of 64% with an average score of 6.0 out of 10 on the review aggregator Rotten Tomatoes, with the site's consensus stating: "What should have been an exciting examination into the origins of an infamous villain becomes a tedious and polluted rendering of legendary Batman folklore in 'The Scarecrow'.
"[3] Matt Fowler of IGN gave the episode a "good" 7.0 out of 10 and wrote in his verdict, "'The Scarecrow' gave us a freaky bit of Jonathan Crane backstory and a good Bruce/Alfred bonding moment, but the rest either didn't make sense, was boring, or worked to undo and deflate previous set ups.
