Doctor Who thought

[beccaelizabeth]

on casting and possible returning

ASH played a character that got blowed up
so was a one off, yes

BUT

he played a *shapeshifter*
who *chose* that form
'a personal favourite'

(one wonders if he's a coffee fan)
(or Buffy fan)
(and if the kids were all 'wah! Giles!')

so

ASH could play someone else
who would be the person Finch was copying

*nods*

pretty!
