There is nothing on this ship that is worth leaving behind a whole life.

"...there's Aerith," Cloud suggests quietly. He feels awful suggesting that Aerith might be worth stalling a return to everything else, but...she's alive, here. Alive and real and warm, and they're closer now than they ever were back home. He doesn't know if he can handle losing her all over again.

Not to mention Zack...and Sephiroth...but those cans of worms can stay safely shut.
