看到的，只是天窗投影的世界。

at the end of S02, Katie wrote the letter to Dan 。。。

It's amazing really, the way we humans behave. The capacity we have 
　　to bring disaster to our lives. The way I brought disaster to ours. It's even more bewildering when you think that all any of us are really searching for is someone to stand beside......someone to look at and say, 'Yes, you make the difference. You bring me peace.' 
　　 
　　I think some people have a gene for love, they know what it is. Giving it and receiving it in return just comes naturally to them.It seems I don't have that chromosome, because being loved by you was,I see now, all I ever wanted.And for some reason,I took it and I broke it.But I believe that love is strong, that love endures, and if it does,then so does hope.
