It's A Thing: Deep Breath

Moffat-Era Tropes: Silurians with hooters and honkers. The Paternoster Gang run through their greatest hits. Scottish jokes. Clockwork droids (who come from the Madame de Pompadour's sister ship). “Don't blink”-type phrase. Companion in love with the Doctor (in this case, Clara having to get over her crush on Matt Smith's version). Everyone's still belting out explanations at each other at lightning speed. Gratuitous reference to a continuity point (i.e., why the Doctor looks like Caecilius from “The Fires of Pompeii”). Dead people's personalities going to some kind of afterlife. The 51st century. "You've redecorated! I don't like it." Timey-wimey (the Doctor telephoning Clara from the past to tell her not to be scared of his new regeneration).

This is what a T-rex looks like.

A Thing in a Thing: A (featherless) T-Rex in the Thames.

The Doctor is A: Long-shanked rascal with a mighty nose.

The Master Is A: ...n egomaniacal needy game-player.

Clara Lies About: How uninterested in male totty she is-- she may have had a pin-up of Marcus Aurelius on her bedroom wall as a teenager, but she secretly fantasizes about hot guy-on-guy action.

Reasons Jenny Should Drop Madame Vastra Like A Hot Potato: She makes her serve the tea, tricks her into posing semi-clad, flirts with Clara, and generally acts like the wife from hell.

Child Count: 12.

The Thick of It: Continued jokes about how ferocious the Doctor currently looks.

It's Actually About: Love-- if you love someone, it doesn't matter if they're a lizard, or a Scotsman with angry eyebrows.
