To me, Dimitri & Kristen still has their DiMera Shares. The reason as to why they still have them is because this pertains to Dimitri, with him knowing that Gabi & Stefan witnessed his shooting, he also he knew that he was blackmailed in order for him to get medical attention, so couldn’t he blackmail them by exposing that they blackmailed him to get them back, hence, as to why he still has them, because he could blackmail them into giving them back to him, given as to how Dimitri was blackmailed out of them. The same with Kristen, with Marlena knowing that what Brady, Gabi & Stefan had put into motion to for GabFan to get Kristen’s shares, Marlena could easily pull the rug out of Gabi & Stefan into giving Kristen’s shares back to her, because they had her granddaughter to be used as a weapon against Kristen, she may not be Kristen’s biggest fan, but still, Rachel is still her granddaughter, she would fight tooth & nail to nail Gabi & Stefan in using Rachel this way, now wouldn’t she? No matter if GabFan got rid of the video.
