While the rain continued it had seemed like the murmur of their voices, rising and swelling a little, now and then, with gusts of emotion.
After those first awkward moments before Gatsby regains his composure, Nick tactfully leaves his own home and stands outside in the inclement weather, taking shelter under ‘a huge black knotted tree whose massed leaves made a fabric against the rain,‘ while Daisy and Gatsby negotiate their sudden reacquaintance. Fitzgerald makes the clever choice to leave the most emotionally charged moments unobserved, and so undescribed by our unreliable narrator – which makes these moments more elemental and enduring, mysterious events like the weather itself. The storm is more powerful for having been unseen, its aftermath the best evidence of its power. Gatsby relays Nick’s obvious news that the rain has ended, and her response has nothing to do with the weather.
‘I’m glad, Jay.’ Her throat, full of aching, grieving beauty, told only of her unexpected joy.
