When Pyke invites Karim and Eleanor to dinner, what does Karim have to consider and who does he go to for advice?

Karim realizes that if he accepts Pyke's invitation to dinner at his household, he will also be accepting Pyke's offer of Karim sleeping with his wife as a reward. Karim asks Eva and Jamila for advice on whether she should go. Eva thinks he should go, since it would help his climb the social latter, and Jamily says it would be just one more step away from Karim's class roots.
