Lush wonders whether Gwendolen is more likely to accept Grandcourt's proposal now out of desperation. We also learn that Lush has been studying Grandcourt for years and has a pretty good sense that he can predict whatever Grandcourt is going to do.
The narrator tells us that Lush knows a few things about Grandcourt for sure: first and most importantly, Grandcourt is not likely to be moved to do anything out of simple generosity.

Grandcourt is like, "Shut up and tell me the truth." Lush is like, "Uh, this is the truth."
Grandcourt wants to know where Gwendolen is going to be the next day. Lush is like, "Hold up, dude – this girl comes with a lot of baggage" (i.e., Mrs. Davilow and the sisters).
They go back and forth a bit, and then Lush is like, "Look, she knows something that you don't know she knows." He tells Grandcourt about how Gwendolen knows all about Lydia – in fact, she met her!
Lush is prepared to tell Grandcourt that he set up the whole thing with Lydia and Gwendolen, but Grandcourt doesn't ask him. He just asks what's next.
