Doctor Who: Every NuWho Companion Ranked From Worst To Best
15. Astrid Peth
Astrid's time with The Doctor was brutally short and truly serves as a tease for what could have been. Kylie Minogue is fantastic as Astrid, the waitress aboard the Titanic who dreams of seeing the stars. The Doctor is immediately drawn to her, seeing the fascination and romance of travel through her eyes.
That their time together is cut so short is a heartbreaking moment for The Doctor. That he is then teased with the chance to bring her back is perhaps even worse, as rather than saving her from her fate, he instead resurrects an echo of what she was, only to let her fade away into space, taking her place with the stars she wanted to see.
She may have only appeared in one episode, yet Astrid made her mark on The Doctor for a long time to come.
