!!Tropes associated with her work:

* ActingForTwo:[[invoked]] In Season 5 of ''{{Series/Angel}}'', she plays both Fred and the demon Illyria.
* ActorInspiredElement:[[invoked]] Dr Saunders of ''{{Series/Dollhouse}}'' was first conceived as an older man. The part was rewritten so that Amy could play it. [[spoiler: Then they ended up revealing Amy was really playing a doll imprinted with the original Dr Saunders personality after he was killed]].
* CareerResurrection:[[invoked]] After the cancellation of ''{{Series/Angel}}'' and ''{{Series/Dollhouse}}'', she mainly showed up in guest star roles on other TV shows - as well as taking time off to raise her children. ''Series/PersonOfInterest'' helped bring her back into prominence.
* PlayingAgainstType:[[invoked]]
** In an episode of ''Series/HowIMetYourMother'', she plays a snarky GranolaGirl.
** The bloodthristy Illyria from ''{{Series/Angel}}'' counts too as a radical departure from the cute nerdy Fred.
** Root from ''Series/PersonOfInterest'' continues to show her range outside her earlier type casting as a CuteClumsyGirl by giving her a main role as a gleefully sadistic TokenEvilTeammate.
* ProductionPosse:[[invoked]] She's appeared in three Joss Whedon projects - ''{{Series/Angel}}'', ''{{Series/Dollhouse}}'' and ''Film/TheCabinInTheWoods''.
* PromotedToOpeningTitles: In ''{{Series/Alias}}'' Season 5.
* ThrowItIn:[[invoked]] In ''Series/PersonOfInterest'', the writers noted her chemistry with Sarah Shahi and decided to play up the sexual tension between their characters.
* TypeCasting:[[invoked]] She tends to end up as a dorky CuteClumsyGirl.
