Yui's in EVA-01.  Asuka's Mom is in EVA-02.  We have no idea who's
in EVA-00, but it's probably NOT Naoko.

Rei is a clone created by combining DNA from Yui and an angel,
probably Lillith.  This enables them to transfer Lillith's
soul - or at least part of it - to Rei, so she was a 
sentient being who did not turn into LCL goo.  Lillith's
soul in her was why Gendo believed he could use Rei to
control Instrumentality; because as long as he had her
alligence, Lillith was in his pocket.

Unfortunately for him, Rei was not a doll, and decided
SHE would determine who she was loyal to...
