Warning: Spoilers ahead for Doctor Who season 14, episode 5, "Dot and Bubble."

Summary Susan Twist remains a mysterious and consistent presence in the Doctor Who season 14 cast, with her character in "Dot and Bubble" standing out for various reasons.

The Doctor and Ruby recognize Susan Twist's character in "Dot and Bubble", marking the first time her character dies, and reveals a connection to another character.

Twist's ongoing portrayal of various characters poses cryptic clues, sparking theories about her true identity.

Susan Twist's Doctor Who cameos have been one of the biggest mysteries of the Disney era, but her "Dot and Bubble" character is set apart from her previous personas for more than one reason. Twist has quietly been one of the most consistent members of the Doctor Who season 14 cast, appearing in every episode of the latest run, including one of David Tennant's installments during his temporary return for the 60th-anniversary specials. However, Twist's appearance in Doctor Who season 14, episode 5, "Dot and Bubble," is something of a landmark for her string of characters.

Doctor Who's Disney era has gone all in on its mysterious aura, with several ongoing enigmas still unsolved. Susan Twist's ubiquity in season 14 is one of the biggest head-scratchers, as there's no obvious connection between all the characters she's been playing. Russell T Davies is playing the long game when it comes to revealing Twist's true identity, but "Dot and Bubble" contains a handful of cryptic clues.

The Doctor & Ruby Both Recognize Susan Twist In Doctor Who Season 14, Episode 5

Most of Susan Twist's previous characters had remained covert until "Dot and Bubble"

The Fifteenth Doctor and his companion first see Susan Twist's face in Doctor Who season 14, episode 3, "Boom." Although they've had opportunities to see her before then, they've both been looking the other way or had other reasons for not laying eyes on the character embodied by the actress. Although Ruby interacts with Twist's Hiker character in "73 Yards," the resetting of the timeline expunges this meeting. So, "Dot and Bubble" is the first time the Doctor and Ruby see Susan Twist since "Boom" and make the connection.

While Ruby can't quite connect the dots on her own, she does recognize Penny Pepper-Bean on some level, who is revealed to be Lindy's "Mummy."

While Ruby can't quite connect the dots on her own, she does recognize Penny Pepper-Bean on some level, who is revealed to be Lindy's "Mummy." However, the Doctor outwardly confirms that he recognizes Twist's latest character by declaring, "She's the face of the ambulance on Kastarion 3." The moment is only brief, and the Doctor sidelines the mystery due to having more pressing matters to tend to. Going forward, any further run-ins with Susan Twist's Doctor Who characters are sure to alert the Doctor even further to the unsolved riddle of her ongoing appearances across time and space.

"Dot & Bubble" Is The First Episode Where Susan Twist's Character Dies

Penny Pepper-Bean is presumably killed by the same monsters shown in the episode

Susan Twist's Penny Pepper-Bean lives on a planet only ever referred to as "The Homeworld." When Ricky September makes use of the "Planet-link" to call said planet so they can mount a rescue mission, the footage shows nothing more than an empty city with one of the episode's monsters overlooking its work. The words, "Homeworld Population: Zero" sit emblazoned on the screen, which means Penny must also have met her end.

None of Susan Twist's previous characters have been entwined enough within the story to suffer any real danger. The closest one that came to being in peril was her Hiker persona in "73 Yards," when she fled the old woman after hearing the mysterious figure say something to which the audience is never privy. While her role as the Kastarion ambulance is particularly prominent, she's portraying nothing more than a computer program, and therefore can't suffer the same risks as her flesh-and-blood counterparts. So, the implied death of Penny Pepper-Bean is certainly new ground for Twist's characters.

Susan Twist's Latest Doctor Who Role Is Directly Related To Another Character

Susan Twist plays the mother of Callie Cooke's Lindy Pepper-Bean

All of Susan Twist's characters leading up to Penny Pepper-Bean have been isolated personas as far as the larger narrative of the episode goes. Penny is the first Susan Twist role with a direct connection to another Doctor Who character within the same installment. Lindy confirms in "Dot and Bubble" that Penny is her mother, meaning Lindy must have known this Susan Twist character her entire life. This means that Penny Pepper-Bean's presence on the Homeworld far predates the arrival of Ruby and the Doctor.

If Susan Twist is simply following the Doctor and Ruby through time, then it would be easy for her to pop in and out of the moments that have previously been shown on-screen. For instance, her Tea Lady role is only a few seconds long in Doctor Who season 14, episode 2, "The Devil's Chord." As Lindy's mother, Penny would have had to stick around for years as her daughter grew up, maintaining a constant relationship in some form or another. So, Penny raises more questions than ever about Susan Twist's ongoing collection of Doctor Who characters.
