What is Nick/Deeley Thinking?

Here are Nick's thoughts:

Actual line: “My mother would have a fit!”
Possible line: “ I can see right through to the other side, wow!” Thinking: “Right, then, all right, then, right, well, there you go, that is it, enough is enough, if you ask my opinion…. I know it is something to do with sex.”

Actual line: “I have my eye on a number of pulses, pulses all round the globe, deprivations and insults…”

Possible line: “ I hate these bloody loafers! Have you seen these revolting things? But at least I have two! And they’re mine!”
Thinking: “ Enough of this British reticence and subtlety. Time to do some good ol’ Chicago shouting! Maybe that’ll help.”

Actual line: “Long Silence”
Possible line: “You can hear the sea sometimes, if you listen very carefully.”
Thinking: “Come on, woman, blink, blink! All right, I suppose you aren’t even going to do that for me.”

Actual line: “Silence”
Possible line: “If I try the Vulcan mind-meld on myself, maybe I’ll be smart enough to understand this play—or at least understand this woman!”
Thinking: “Phew, we have reached the final tableau, the cage of infinity, I am a teary, nose-drippy mess, my character’s life is in tatters, his emotions are flayed, his psyche shredded—aah, it’s just one more night in the theatre… I believe I’ve earned this drink.”
