Therefore, the title is literal, metaphorical, and real-world based. Literally, the title stems from the fact that the battle with Rigon, in the Mediterranean, around the Earth, and around the galaxy truly is the final test for the recruits. Metaphorically, it refers to the battle with Rigon being the end-all, be-all of the Elite's plans, and determines if they will succeed or fail. In the real-world, the episode serves at the series finale, and therefore is somewhat of a final test for the staff.
