Doctor Who: 10 Best Companion Performances In NuWho

10. Arthur Darvill (Rory) - The Girl Who Waited

While The Girl Who Waited seems to be primarily about Amy (she is the character referred to in the title, after all!), Rory's role in proceedings is also important to how the storyline pans out, and Arthur Darvill does a compelling job showing just how the character reacts to events.

Rather than doing anything showy, he lends a steady hand to proceedings. He's understated in his actions and delivery, but he still gets across the sense of just how much Amy means to Rory.

Of course, that's part of his usual performance as Rory, but he does showcase some of his other talents here, too. Rory has to go through a wide range of emotions and Darvill capably captures them all. He shows his frustration and anger when he first encounters old Amy because the Doctor has messed up and his humour is on display too. His delivery of lines like "Good question. Bit sinister. What's the answer to not get us killed?" works to draw laughs whilst keeping the dialogue fresh and interesting.

However, the most defining moment of this episode for Rory comes at the end. It's the note of disgust upon challenging the Doctor when the Time Lord forces Rory to choose which Amy he wants to live with. It makes the ending  poignant and chilling, a testament to his ability.
