hehe.. from wat i noe is.. those ball to demolish building.. is
using a force to swing the ball.. so u noe lar.. swinging.. &
wan to pull back.. or pull away.. very hard de.
i oso interpreted that hasty key is return to actual time: when jay
playing hasty key, he will return to his current time, & when
rain playing hasty key, she will return to her past.
so that y when jay played hasty key, he remain at his time. thus
kana hit & die lor..
& one more thing is.... rem when rain taught jay to play that
song, she play super fast... & her face very strange.. i got a
feeling, she knew that jay can learn piano keys very fast, so she
purposely play fast, so he cant go back to the past to look for
her, when he knew the truth...
