In the scene where Dana confronts her rapist, you can see that she is now wearing the "fearlessness" necklace that Olivia has been wearing for most of the series. Olivia still has the mandala necklace on. Both necklaces are from Mariska Hargitay's Joyful Hearts Foundation.
The name Dana of agent Lewis and the name Gillian of A.D.A. Hardwicke refere to the FBI agent Dana Scully (Gillian Anderson) from the series The X- Files.
