She is the daughter of Pennywise and was brought up by him and incorporated into all of his evil ideas. She's a part of the whole thing. It's a transformation.” Did you come up with a childhood for her?
Kersh is Pennywise's daughter.
His name was Robert Gray, better known as Bob Gray, better known as Pennywise the Dancing Clown." This is also the name It uses to introduce itself to Georgie, Bill's brother, in the novel.
Kersh" begins to reveal that she's actually one of Pennywise's horrific manifestations - a twist that doesn't seem to bode well (at all) for Beverly. The way that director Andy Muschietti composes the scene, and captures the slow crescendo of horror and anxiety with this old lady character is pretty masterful.
Bev goes to visit her childhood home, quickly learning from its elderly resident that her father had passed away years earlier. It's revealed this is Pennywise himself, disguised as an old woman and, in the miniseries, Bev's father.
Beverly "Bev" Marsh is a fictional character created by Stephen King and one of the main characters of his 1986 horror novel It.
In the novel, It's origins are nebulous. He took the form of a clown most frequently, Mr. Bob Gray or Pennywise, but his true form is an ancient eldritch entity from another universe who landed in the town that would become Derry by way of an asteroid and first awoke in 1715.
It feasts on the flesh of humans simply because our fears are easy to manifest and they make us taste better. According to It, when humans got scared, "all the chemicals of fear flooded the body and salted the meat".
When this scene between Mr. Marsh and Beverly occurs in the novel, King makes it clear that Bev's father is actually possessed by It. It takes the shape of whatever its target fears the most, so Mr. Marsh is used as a conduit to embody Beverly's worst fears of abuse.
Still, the film gives viewers a pretty good sense of who Bill (Jaeden Lieberher), Beverly (Sophia Lillis), Ben (Jeremy Ray Taylor), Richie (Stranger Things star Finn Wolfhard), Eddie (Jack Dylan Grazer ), Stanley (Wyatt Oleff), and Mike (Chosen Jacobs) are.
In the novel, It claims that its true name is Robert "Bob" Gray, but decided to be named “It”. Throughout the book, It is generally referred to as male due to usually appearing as Pennywise.
Kersh (portrayed by Florence Paterson in the IT (1990 miniseries)), and Joan Gregson in It: Chapter Two, also known as Gray Kersh, was a secondary form of It created to scare Beverly Marsh, one of the novel's protagonists into leaving Derry before he was going to kill them all if they stayed.
Red balloons are Pennywise's calling cards, and he often uses them as bait to kidnap children.
It was said on page 1361 that the Spider being both female and pregnant was a symbolic interperetation. Its not literal, but a representation of whatever equivalent but inconceivable reproductive capability It actually has. Pennywise didn't become pregnant.
Beverly's father can't see any of the blood in the bathroom. On one level, this is because he's an adult; a major theme of It is that the innate power of childhood and ability to remember childhood fears serve as a crucial weapon against It.
In the adaptation of It Chapter Two, Richie is portrayed as being secretly in love with Eddie Kaspbrak until the latter's death, and Eddie remained unaware of these feelings.
At least, not at first. After Bev is kidnapped by Pennywise and dragged down to his lair, the demonic, shape-shifting clown holds her up in the air by her neck and opens its jaw all the way back so she's forced to stare deep into its throat.
The cinematic adaptation of Stephen King's IT Chapter Two depicted the satisfying death of Pennywise while subtly hearkening back to Pennywise's first 1988 victim, Bill's brother Georgie.
Some spoilers for It (movie, 2017) are below.
His phobia seems to stem from a mental illness his mother suffers from known as Munchausen syndrome by proxy, which manifests in her relentless “worrying” about his health.
Throughout Stephen King's It, Pennywise is referred to as a male, but author Stephen King pulled a fast one on readers in the It book ending by revealing the creature's true form was a pregnant spider, implying that it is, in fact, biologically female.
Stephen King's 'IT' introduced readers to a one-of-a-kind creature that can take any form, the most common one being Pennywise the Dancing Clown, and as menacing as it is, this creature has one big enemy it's truly scared of: Maturin, the turtle.
It's weaknesses are courage and heart. For the sake of spoilers, I won't go too much into the Ritual of Chüd, but suffice it to say that if you want to defeat It, you've got to have the two traits listed above.
The 27-year cycle refers to the extended interval between waking periods of the extra-dimensional shapeshifter in the novel IT, as well as the interval between occurences of The Troubles (outbreaks of increased supernatural activity) in the television series Haven.
