Heather, Doctor Who
Heather (Stephanie Hyam)
Heather was a guest character who appeared in season 10 episode 1 as a romantic interest for new regular character Bill Potts. Bill spotted her at a bar, and was instantly attracted. She saw her again on campus, and the girl introduced herself as Heather and 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 Bill saw Heather, still staring at the puddle, she said she’d show her 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).
