these are the possible endings i thought of...

**tidus awakes in the water near luca because yuna whistled so he'd
come to her

**tidus is swimming in the farplane waters

**tidus wakes up after the whole zarnarkand and auron(beginnning
movie) and realizes he'z in the water near zanarkand

**tidus wakes up in water somewhere and realizes it was all a dream

**tidus is brought back to life by the jecht, braska, and auron
because they want tidus and yuna to be happy because they are in
love

um...yeah i know that was pretty lame but oh well it's all i could
think of
