[Waltzing in, and via the door rather than a whooshing blue box] [As he's being busily announced by his tux-clad escort, the Doctor contents himself with observing the scene. And his brow quickly clouds as he notes the intimate closeness of Booster and the beautiful woman commanding the center of the room. A creature of power, most likely his prime suspect. He uses the screwdriver inside his coat to confirm, then steps fully forward into the light.]
Well, Booster, here I am, hope I haven't kept you...all...waiting long? Nightwing, have you joined the search, then? And...brought a brother?
[Stepping forward toward Talia but stopping short when Booster bristles behind her.]
And you, madam, I don't believe I've met you..in the flesh. I'm The Doctor.
