Notes
结局是温暖的，抚慰人心的，这反而比Lydia不知哪里来的自信导致溺死在湖中和Jack处心积虑隐藏自己的同性取向，更让我意外。
父亲James和母亲Marilyn终于注意到了小女儿Hannah，母亲的怀抱和父亲的肩膀给了她难得的亲密感和安全感。James决心回归家庭，Marilyn意外地接受了他。他们互相安慰彼此，修正对彼此的认知，重归旧好。
哥哥Nath不顾Hannah阻拦，还是给了Jack一拳。这一拳对于Nath来说，是发泄无处释放的愤怒和‘背叛’Lydia的愧疚；对于Jack来说，是爱，和为了满足Nath发泄的欲望做出的牺牲。
Hannah明白这一切，她挡在Jack身前，推开哥哥。Nath任由自己的身体倒入湖中。湖水的冰冷，黑暗，和窒息感，让他想起Lydia，他要记住这一刻，这就是Lydia死前经历的一切。巧合的是，Hannah也曾在夜里躺在冰冷的湖水边，想象姐姐在湖里的感觉。Nath此刻也许不会记得自己曾经把Lydia故意推进湖里，又很快把她救了出来；他更不会知道，Lydia把自己用同样的方式推向死亡，有多大程度上，是为了和Nath赌气，为了割裂对Nath的依赖，为了证明自己。
