Bob is getting into trouble with the mob. They've decided to send hit men after him and the episode ends with him packing his bags and leaving. The next episode begins with bob on a beach with Alice, discussing the time he was chased by mobsters and the events leading up to it. Then it cuts back to the action, and Bob is still packing his bags to skip town.
In this case, the situation has lost all tension, because we know that Bob survives and goes on to discuss it with Alice at a later date. Until that date arrives, Bob is effectively un-killable.
This trope is slightly different from Plot Armor because it involves the way the story is told or framed, rather than how the story itself happens.
