How we cite our quotes:
Quote #1
BRUCE: Even ten minutes is a long time to be away from you.
HILDY: What did you say?
BRUCE: What?
HILDY: Go on. [He laughs sheepishly] Well, go ahead.
BRUCE: Well, I just said, "Even ten minutes is a long time to be away from you."
HILDY: I heard you the first time. I like it. That's why I asked you to say it again.
Bruce speaks directly; he tells Hildy he loves her. Walter has trouble doing that. Hildy seems to like the direct approach… but notice that she first pretends she hasn't heard Bruce. Like Walter, she's addicted to misdirection (to poor Bruce's misfortune).
Quote #2
HILDY: Walter, you're wonderful. In a loathsome sort of way.
Hildy seems to insult Walter… but she also compliments him. She's conflicted. Love; it's complicated.
Quote #3
WALTER: Any way we can stop the 4:00 train to Albany.
DUFFY: We might dynamite it.
WALTER: Could we?
Presumably Walter isn't serious here (is he?). But his willingness to resort to violence is typical of his approach to love. He sees it as a campaign; which may involve kidnapping, skullduggery, and the occasional blown up train.
