"You're not a doctor. I'm a doctor. Far as I'm concerned, you have to earn that title!" -- Martha Jones.
You GO, girl! I knew I was going to love Martha.
One of my favourite moments of this episode is when Dr. Jones checks "Mr Smith's" heartbeat. Then she checks the other side...and hears another heartbeat.
She glances up and locks eyes with "Smith".... and THE DOCTOR winks at her!
From that moment on, I was hooked.
I'll never look at a bendy straw the same way again.
