I saw the show. Had I known, I would've taken notes. From what I remember: Marlena and Kate are at Brady pub discussing Hope and John's "relationship", bringing us to a lot of flashbacks from 9 months ago, when Stevano and Kate were talking; Kate found out that Hope was actually Gina and was told she should keep her mouth shut otherwise.
Jennifer, Jack and Abby all went to the station to try to trigger her memory back by looking at the security footage; while they are there Rafe gets a call that Rolf was seen and off he goes. In the meantime, Stevano is talking with Rolf explaining that they had the forensic person replace Gina on the security tape with Rolf, as they needed someone easily identifiable.
Show ends Rafe and another cop knocking on the loft door, Gina and Stevano looking like they are trapped.
