How we cite our quotes: (Part.Chapter.Paragraph)
Quote #4
But it was also obvious the man could not live by work alone. (2.4.3)
Jude can justify it any way he wants, but he is in love with Sue from before he even talks to her. This whole needing to do stuff other than work is just an excuse to see her as often as he possibly can.
Quote #5
She had not the least conception how the hearts of the twain went out to her (2.5.16)
(By the way, the "twain" in this passage is Jude and Phillotson, caught up in their efforts to win Sue's heart. "Twain" just means two people here.) Ugh! One of the most appealing and most aggravating aspects of Sue is that she is just oblivious when people are in love with her. This causes Jude and Phillotson (and Sue, for that matter) quite a bit of heartache down the line.
Quote #6
'I don't know if I am vexed or not. I know I care very much about you!' (3.4.45)
You gotta love vaguely repressed Victorian proclamations of love (or at least proclamations of serious like). Jude is saddened to hear that Sue once had a pretty intense emotional affair with a "scholar friend" before meeting Jude or Phillotson—but he still "[cares] very much about" her! Considering how much Jude gives up for Sue, we think that a stronger word than "care" might be required here.
