Some of the elements which can be considered to be gothic in "the pit and the pendulum" are darkness, internal struggle, horror and terror experienced by the main character, lack of freedom, torture, etc.
There are five elements of a plot: Exposition, conflict, raising action, climax, falling action and Resolution. From these elements, the one that approaches best to that excerpt is Resolution. The word "finally" can be a signal word that denotes the ending part and Resolution means that the conflict has been solved and indicates the ending, which it really makes sense, since after all the things happened in Jake's life, at the end "I expect we'll need three servings of bacon today" refering maybe to a happy ending.
When Romeo says “he jests at scars that never felt a wound” he’s basically saying that it’s easy to make fun of or joke about others scars or hurts, especially if you have never experienced that type of hurt. Basically, he uses it to describe the apathy of Mercutio when he overhears him joking about Romeo’s short-lived love and devotion to Rosaline.
