If something happens to the Doctor like he's scraped up or hurt or SOMETHING, it would melt the ice around Clara's heart because she'd be compelled to take care of him. IDK IF HE WOULD LET HER, BUT.

For the troop prompt, Clara's gonna see some of her echoes die, maybe we could come up with something especially traumatizing for the Doctor. EXCEPT HE DOESN'T REALLY REMEMBER ANYTHING so idk how that would even go sdfjsdg.
