With how any DeMira feels about each other, no matter if they do warn each other of upcoming threats to members of their own family from any family member, i.e. when EJ tried to warn Gabi & Stefan when it came to Megan, I can’t see anyone them asking to pass the salt, I can’t see how it would come up at the DeMira family dinner table, now can you, especially with how it was put out there that it was absurd for the writers to bring it up since it happened long ago, especially when Stefan first showed up was way after the Necktie Killings, don’t you think?
