Bill Potts, Doctor Who
Bill Potts (Pearl Mackie)
(Season 10, episodes 1-6)
Bill Potts is the Doctor’s newest companion introduced in Season 10, a university canteen worker who sneaks into the Doctor’s lectures. Bill is smart, energetic, quick with a joke and excited to go on adventures with the Doctor. As the Doctor’s companion, she gets a lot of screen-time, and is central to the plot.
The Doctor notices Bill in his lectures, finds her interesting and decides to become her tutor. Her interest in women came up in her first scene, when she told the Doctor about a girl she always gave extra chips to, in order to get her to notice her, until eventually she realized she had made her fat.
When trying to explain to her foster mother that the Doctor was her “foster tutor”, and she was warned to keep an eye on men, Bill quipped “men aren’t where I keep my eye, actually”.
At a bar, Bill spotted a girl with a star in her eye, and was instantly attracted. She spotted her again on campus, and the girl (Heather) showed her a mysterious puddle that showed the wrong reflection and that wouldn’t disappear even though it hadn’t rained for weeks. The next time she saw Heather, still staring at the puddle, she said she’d show Bill what was wrong with the reflection and promised her she wouldn’t leave. As Bill turned around, Heather was absorbed by the puddle.
The puddle, taking Heather’s shape, started to chase Bill who ran to the Doctor for help, and they both escaped in the TARDIS as the puddle started chasing them through space and time, until Bill realized Heather’s promise had been driving the creature. Bill reached for Heather’s outstretched hand, bid her goodbye and let go. After that, Heather washed away.
Heather wasn’t human anymore and her fate was unclear since she still existed as part of the mysterious material. The Doctor’s final line in the pilot was “It’s a big universe, but maybe one day we’ll find her”, but she was not mentioned again (episodes 1-5).
At end of the episode Bill convinced the Doctor not to wipe her memories, and stepped into the TARDIS again.
After the introduction episode, Bill and the Doctor go on adventures together. In episode, 2, Bill chose to go to the future, to “see if it was happy”, and they ended up at a future colony. In episode 3 they went to the past, at the end of London’s last frost fair, and in episode 5 to space on a mining ship.
In episode 4, Bill moved in with several other students. When one of the male roommates tried to hit on her, she told him she was only interested in girls. In episode 6 she was back home saying the roommate situation hadn’t worked out. She brought home a date, just as her mother was telling her she had “very strict rules about men” in her house. Bill replied with: “not as strict as mine”.
As Bill was telling her date, Penny, that whatever was happening between them was nothing to feel guilty about, the Pope showed up, scaring Penny off, and Bill had to go talk to the Doctor and deal with the new case of the week.
