The following is a sentence from an analysis by Sarah Dillon of a passage of Elizabeth Bowen’s A World of Love.
The fact that the tree’s a chestnut then promises in its symbolism the potential reinvigoration of a marriage that we then find gestured towards in the rest of the passage.
I can't understand how the relative clause "that we then find gestured towards in the rest of the passage" works. It seems that the clause modifies "the potential reinvigoration of a marriage". Is it the object of "find"? Or is it the object of "towards"?
