LANE: He [Henry] left a message. I listened to it eight-and-a-half times, but then my mom came home and I had to erase it. But I was so panicked that I broke it, which is better because now all evidence that a boy called me is in the trash.
RORY: Eight and a half times.
LANE: Well, it was a good message the first couple times. Then I started parsing it for subtext.
To parse a sentence means to analyse it by reducing it to its grammatical elements, while subtext is the underlying meaning of a particular text. In other words, Lane began picking apart everything Henry said to search for hidden meanings.
