来自《记忆碎片》105分Teddy与Lenny的对话:
Teddy:I gave you a reason to live, and you were more than happy to help.
You don’t want the truth...
You make up your own truth. Like your police file.
It was complete when I gave it to you. Who took out the 12 pages?
Lenny: You, probably.
Teddy: No, it wasn’t me. See, it was you.
Lenny: Why would I do that?
Teddy: To create a puzzle you could never solve
...
Lenny: I’m the one that put it all together.
You, you wander around, you’re playing detective.
A dead wife to pine for.
A sense of purpose to your life.
A romantic quest that
you wouldn’t end even if I wasn’t in the picture.
由上面对话可知,Lenny一直都是活在自己想要的现实中——为妻子报仇。由于受到了生理(被敲打头部)以及心理的创伤(妻子被强奸,并且认为妻子已经死亡)导致Lenny在那件事情之后只剩下短期记忆,在记忆中的最后一个念头就是给妻子报仇。尽管他已经在Teddy的协助下,将强奸他妻子的真正凶手杀死,但是由于没有长期记忆,所以他并不知道自己已经复仇。
由Lenny与旅馆馆主的对话可知,Lenny在入住之初就跟馆主说过不要将电话接到他的房间内,除了Teddy的电话。所以Lenny一开始身在跟Teddy打电话,电话中的Sammy,后面Lenny与Teddy的对话中,可以推测,Sammy其实是Lenny的一个对投射,是Lenny杀死了自己的妻子。
Teddy熟知Lenny的习性,因为他不是杀手(对自己杀人并没有印象,但身体有记忆),所以他很在行去杀人。Teddy利用Lenny的复仇去去人获取钱财,所以在电话中以及利用前警察的身份给一些“James G’s”的信息Lenny,让他去杀死一个个毒贩从而获得利益。
