Sonia Kaspbrak

Sonia Kaspbrak is a character in Stephen King's "It".

IT - Chapter 1 (2017)
In "It", from 2017 and "It - Chapter 2", from 2019, Sonia is played by Molly Aktinson.

Sonia Kaskpbrak, also known as "Ms. K", is the mother of Eddie Kaspbrak. We see Sonia for the first time in 2017's "It", when Eddie, Bill and Richie go to Kaspbrak's residence to pick up some cookies. Sonia is watching television and doing her nails. Upon seeing the three boys leaving his home, Sonia questions Eddie about the reason for his departure; Bill tries to answer, but starts to stutter, being interrupted by Richie, who claims that Bill had won a croque kit. Sonia, still a little suspicious, tells Eddie that he should not play on the grass, as it can cause allergies. Ms. K also questions Eddie if he is not forgetting something, referring to a kiss from his son. These attitudes immediately reveal Sonia's hyperprotective character with her son; a fact that we would see later in the movie.

We didn't see Sonia for a while, seeing her again only in the middle of the film, when "Losers Club" is returning from her meeting with IT, at the abandoned house on 29 Neibolt Street. After a confrontation with Pennywise, Eddie breaks his arm falling from the floor of the house, being helped by Richie, who repositioned his friend's broken bone. After leaving the house, already on the streets of Derry, we see Sonia holding Eddie and blaming the losers for her son's fracture. Mrs. K, very nervous, puts Eddie in the car and, accidentally, drops the keys to the floor. Gently, Bervely tries to pick up the key from the floor, but is interrupted by Sonia, who, in an act of cruelty, orders her to leave, then utters the phrase: "I've heard about you, Miss Marsh, and I don't want one dirty girl like you touching my son". Then Bill tries to reason with Sonia (presumably to tell more details about It), but Kaspbrak interrupts Bill and calls the losers monsters, also asking them to stay away from Eddie. Sonia leaves with Eddie, heading for the hospital shortly thereafter.

Just before the final battle against Pennywise, with his cast already on, Eddie goes to the pharmacy, and finds out through Greta, who discovers that his medicines are only placebos. After receiving a call, Eddie tries to leave the house to meet his friends, but is interrupted by his mother, who is very reluctant to let her son out, and says that he is recovering from his illness, which turned out to be non-existent. Upon hearing his mother, Eddie confronts Sonia, stating that his drugs are placebos and throwing them on the floor. Ms. K said she wanted to protect him, but Eddie claims that his true protectors are his friends, running off shortly afterwards, leaving Sonia desperate. This is the last time that we see Eddie's mother in 2017's "It".

IT - Chapter 2 (2019)
In "It - chapter 2", Sonia is mentioned by Eddie, when he, as an adult, goes to Mr. Keene's pharmacy. Eddie, when asked by Keene about his mother, claims that she died of cancer of her liver. In this same film, we are surprised by a flashback of Eddie as a child, in 1989. In this flashback, we see Eddie in the basement of Keene's pharmacy, which at the end of a long corridor, contains a room with a curtain that is used as a door. Eddie hears his mother's screams calling to him and, after a tension, he opens the curtains and finds Sonia trapped on a stretcher. Mrs. K is desperate and calls for Eddie's help, saying that someone is approaching. After a sound of chains, we are directed to the end of the room, which, in the middle of the darkness, we see someone covered with a black cloth. Shortly after, this hidden being turns out to be the leper that scared Eddie in the first film. This fact demonstrates that this is a flashback to an illusion created by Pennywise. Gradually, the leper approaches and, at the same time, Sonia begs to read free, but Eddie is unable to free her in time. The leper then advances on Sonia, introducing the tongue into his mouth, "infecting" it with leprosy.

Personality
Sonia is an overprotective mother, but this trait made her arrogant. Kaspbrak does not believe his son's friends, Eddie, and thinks they are to blame for his son's illness. Sonia, despite loving her son very much and wanting to protect him above all else, her arrogant character in the face of everything and everyone ended up becoming a reason to be a character seen with bad eyes by fans.

Appearance
Sonia is a woman with green eyes and short dark hair. This one wears glasses, but only uses them once during the film, being mostly without them. Ms. K is of medium height, but overweight; a fact that, unfortunately, may have led to his death, with cancer in his liver.
