“How about that then?” The Doctor throws open the TARDIS doors and steps aside, so Martha can get an uninterrupted view.
“Oh my God!” Martha takes a step back, suddenly nervous, both hands rising to her mouth.
“It’s alright, come closer, you won’t fall out.”
“Well, if you’re sure.”
“I promise; it’s perfectly safe.”
Martha cautiously steps forward again, into the open doorway, and stares out at the nebula before them in space, a hazy, glowing cloud of gas and dust, seeming to glow from within.
“It’s incredible!” She doesn’t think she’s ever seen anything so amazing in her life.
