Big news! Mr. B has told Pamela he's no longer going to treat her as his servant because he looooooves her: "I must say I love you; and have put on a Behavior to you, that was much against my Heart, in hopes to frighten you to my purposes" (33.4).
Also, he wants to help out her family, no strings attached. SURE. Seems legit.
He just wants her to stay another week or two so he could get some "certain Affairs" in order (33.6).
