According to TVLine, Mallory Jansen (Galavant) has been cast to play AIDA (Artifical Data Analyser), the disembodied voice we heard at the end of season 3… except now it will be embodied. In the comics AIDA is created by the Squadron Supreme's Tom Thumb but in the MCU she is created by Holden Radcliffe (John Hanna).
Jansen played Madalena, the rather selfish ex-girlfriend / Queen on Galavant. She was also in two other television series over the last two years: Baby Daddy and Young & Hungry as well as playing supermodel Helena Christensen in Never Tear Us Apart: the Untold Story of INXS.
Marvel's Agents of S.H.I.E.L.D returns September 20th.
