What to expect on Days of our Lives

Theo (Tyler Joseph Andrews) manages to get Jada (Elia Cantu) to join him for another night of trivia at the Brady Pub, but things don't quite go as planned when their date is interrupted. In fact, he appears to be on the phone with Abe (James Reynolds) when something goes terribly wrong.
The next thing Theo knows, he wakes up in the DiMera crypt to find his aunt and uncles standing over him. When Chad (Billy Flynn), Kristen (Stacy Haiduk), and Tony (Thaao Penghlis) see Theo, they realize that DiMeras are being hunted and targeted, but they have no idea why. If they can figure out why they are there, then maybe they can find a way out.
The DiMeras start to put their heads together and strategize. There has to be a good reason why they are all there. Someone went to a lot of trouble to kidnap Kristen from jail, so whoever did this means business. Does this crypt story have anything to do with what EJ (Daniel Feuerriegel) is up to in his secret hospital lab?
Cat means business

While Dr. Rolf (Richard Wharton) and Mark Greene (Johan Robinson) are hard at work in that lab, Cat Greene (AnnaLynne McCord) is hard at work trying to bring EJ down. She uses the fact that they were in the same Italian clinic to get EJ to confide in her, but she also needs a little extra help. When EJ isn't looking, she slips something into his drink that loosens him up a bit.
Cat does her best to question EJ and see what he might slip and tell her, but EJ is much more interested in learning more about that time in the hospital when he was covered in bandages and could barely move.
Once EJ is finally unconscious, Cat does even more snooping and makes her way into the DiMera tunnels. One never knows what she will find there because it is a never-ending maze full of secrets. Will it lead Cat to the crypt and the other DiMeras who are trapped?
