I find it ironic that Leo has a unique preference for the daughter of a Titan. For starters, Leo has always been interested in the girls that are way out of his league- Thalia, Kionne, Calypso- What he needs is a morale booster.

As the Chief Engineer of the Argo II, Leo has many responsibilities to uphold- like keeping the ship from burning up and crashing to the earth. However, I find that Leo feels out of the loop, unlike the other six half-bloods, who all have love interests. perhaps the most misconceived thought that everyone keeps talking about is Leo dying in Blood of Olympus- If he dies before the ship A.) Arrives in Greece, B.) Completes the Mission, and C.) Begins its flight home, The following occurs:

A.) The likelihood of any of the remaining seven surviving the war diminishes quickly, a broken ship that can't be repaired is doomed to sink in short order. The Seven may complete the mission, but they'll need a new way home.

B.) Assuming the ship is relatively flight-worthy, the remaining half-bloods could pull off the mission and arrive home before a bloody conflict erupts between the Greek and Roman camps.

C.) If Leo died just before taking off for home, the seven will reach the camp, but should they encounter a problem requiring a repair mid-flight, they could be in for a real nightmare, especially if the power core of the Argo II had begun a leak. remember the explosion that the Trio prevented in the Half-Blood Diaries, the one with Buford running away? Yeah- Mini-Nuke bad.

however, I'm being hopeful that Leo survives and later frees Calypso from her cursed island. It would be tragic to see the pained look on the girl's face to find out 5 years later- "He isn't coming..." That would be horrible.
