“It’s… smaller on the outside…” you gasped, walking into the TARDIS and looking around before glancing back outside, making sure you were seeing it correctly.

The Doctor paused at your words, his smirk dropping instantly. He was looking forward to showing you the inside of his ship as he always enjoyed the human wonder but… you said it wrong. Almost everyone had the same reaction but… you said it… wrong. You said it like Clara.

“Right, okay…” He murmured, furrowing his eyebrows softly. He couldn’t quite decide how to feel. He’d only just been able to find the courage to invite another human into his TARDIS after what had happened to Clara and now-…. No. Just because you said a few words similar to Clara had and differently to everyone else, didn’t mean you were going to end up like her. It just didn’t.
