The fifth episode of It: Welcome to Derry is jam-packed with new information, offering the clearest look yet at Bill Skarsgård as Pennywise. Still, with such a dense narrative packed into a single episode, a subtle reveal might have been overlooked completely, and it's a aspect that deserves attention.
After Jovan Adepo's character uncovers that Derry is essentially a mystical prison for an ancient evil, he promptly gets his family out of town to the military installation on the outskirts. We also learn that Stephen Rider's character bus to Shawshank State Prison was attacked. Later, viewers find him in the back of Madeleine Stowe's character car. At first, it appears he's taken her hostage as a means of getting out of town. However, once in the woods, the two share an intimate kiss.
Hank claims the bus was attacked (presumably by the sinister clown), allowing him to escape. He then asks Ingrid to find someone who can help him demonstrate his innocence for the murders at the movie theater.
At the conclusion of the installment, Ingrid makes contact to meet with Mrs. Hanlon, who is already interested in Hank’s case. It is at this moment that Ingrid looks directly into the camera and reveals her full name.
“Mrs. Hanlon, my name is Kersh, Ingrid. You don’t know me, but we have a shared acquaintance,” she says.
If that surname is recognizable, it’s because a character named Mrs. Kersh appears in the It novel, as well as both the It miniseries and It: Chapter 2 film. She’s the elderly lady that Beverly Marsh mistakenly visits, who eventually turns out to be one of the clown's numerous disguises. However, Welcome to Derry implies that the character was a actual individual, not just a illusion created by It. Whether Ingrid is the daughter of this character or the same person is not yet verified, but it's entirely possible that Ingrid and Mrs. Kersh identical.
In It: Chapter 2, which exists in the same timeline as Welcome to Derry, Mrs. Kersh has a couple of clues: the way she enunciates the word “father” and the line “nobody in Derry ever really dies,” both of which Ingrid has uttered, respectively, throughout the season, in a comparable rhythm to the film.
If Mrs. Kersh is indeed an actual person and not just a disguise of the entity, it will spell trouble for Ingrid, especially as she seeks to untangle the conspiracy behind the theater murders. Of course, we already know that the entity is to blame for the killings. That means the likelihood is high that she — along with her companions — will likely cross paths with the otherworldly being.
In a earlier discussion, Stephen Rider noted how pleased he feels about the latest story developments and that his character is receiving richer layers. "I play Black characters on screen, and a lot of times you don’t get all the meat, you just deliver background information," he says. "For him to have that internal secret --- as actors, we have to create those secrets for ourselves. [...] But Hank has that."
With only three episodes left, expect more storylines to collide as the season barrels toward its finale. After the disclosures from the latest episode, the truth about who Ingrid is shouldn’t be far off. And if she is indeed the same person, Ingrid will join the extensive roster of doomed characters fated to become entwined with Pennywise for generations to come.
