PROBLEM: Izzie Stevens -- Izzie makes a treatment error that endangers the life of a patient, and is fired from the hospital's surgical program. Believing Alex is partially to blame, she writes him a Dear John letter and leaves. Izzie later learns that Alex was not responsible for her lost job, and returns to make amends with him, but Meredith informs her that Alex is moving on. Izzie informs Alex that she no longer has cancer. Although he is pleased, Alex officially breaks up with Izzie, telling her that he loves her but deserves better. She leaves Seattle to start fresh. Several episodes later, Alex informs Meredith that Izzie sent divorce papers, which he signs in the episode ``How Insensitive''. In the sixth-season finale, Alex is shot and asks for Izzie. Imagining that Meredith's half-sister Lexie (Chyler Leigh) is Izzie, he apologizes and asks her never to leave him again. In the 300th episode, Alex reveals he never found out what happened to Izzie, but envisions a perfect, happy life for her, always smiling, now that he has moved on.

PROBLEM: Mariana Trench -- Four descents have been achieved. The first was the manned descent by Swiss-designed, Italian-built, United States Navy-owned bathyscaphe Trieste which reached the bottom at 1:06 pm on 23 January 1960, with Don Walsh and Jacques Piccard on board. Iron shot was used for ballast, with gasoline for buoyancy. The onboard systems indicated a depth of 11,521 m (37,799 ft), but this was later revised to 10,916 m (35,814 ft). The depth was estimated from a conversion of pressure measured and calculations based on the water density from sea surface to seabed.
