Companion: Clara

Story: If Clara's not being tied up in an alien desert and left for dead (or for the sand piranhas), or taking a whirlwind trip with the Doctor to visit the Fish People, she's headed out with Danny for dinner, drinks or an invigorating morning run. Juggling TARDIS travel and daily life begins to take its toll on an exhausted Clara, especially because she's trying her very hardest to keep Danny secret from the Doctor, and her time-travelling hobby secret from Danny.

Then, one day, during a perfectly ordinary teachers' meeting, her carefully-constructed and precariously-balanced life threatens to come toppling down around her, when she learns that the new caretaker at Coal Hill School is none other than the Doctor.
