Re: Your own personal continuity
In the TNG episode Coming of Age, Riker asks Picard if he's under investigation. He's asking this because years before as an ensign, while on board the Pegaus, he took part in secret experiments that resulted in the loss of the ship. A fact that only comes to light years later in The Pegaus. The loss of the Pegasus is a dirty secret he's been waiting to come to light for years - hence his question when Remmick comes aboard in Coming of Age.
I like that one.
