I'd just like to reiterate here that Paige looks really quite different from how she did back in high school, to the extent that the less observant characters might not realise it's her at all until they're told, and even those who do recognise her will do a serious double take when the penny drops.
Paxton: Wow... you sound just like an old friend of mine from high school
Paige: Paxton, it's me Paige
Paxton: (Confused Silence)
Paxton: You even have the same name, are you like...a clone or something?
Paige: -_-
