never could trust chipmunks. always playing detective when one's not looking.

as to Blink, in theory, there's no reason why the Doctor couldn't go back (once he gets the TARDIS) and pick up Billy.
...in practice, this is the man who once took eleven+ years to "be right back"...and has more than once forgotten things.
(on the gripping hand, its also possible the Doctor went back, and Billy didn't want to leave)

I hope your weekend (and this ensuing week) are superb.

my weekend was far too hot. watching Perception now. am wondering who gets bigger headaches - Detective Murphy or Detective Moretti.
