Your school had a huge swimming pool that some of the students would swim in after classes. Your "friends" had wanted to swim in the pool. You were just at the edge of the pool watching some of your friends, when one of them push you over. You fell in, you were struggling to keep afloat. When your vision got blurry, the last thing you saw was Alhaitham until you blacked out.

you woke up to see a white wall, you then look to your left to see Alhaitham leaning against the wall.
