I assume that Darcy's destination when he left Rosings (or left the drawing room?) was unknown to the others.

I believe we would agree on that.

]Is there something in the text that leads you to believe otherwise?

No, not in JA's text, in yours. I was responding to your speculation. I speculated that Darcy, upon hearing Mr. Collins' report of Lizzy'sillness, possibly exaggerated out of fear of Lady C.'s censure, became alarmed enough because of his feelings for her to go check up on Lizzy on his own. It was your suggestion that Darcy would take Charlotte aside (or failing that that the Col. would speak to Charlotte ouside of everyone's hearing except Darcy's) to inquire after specifics that he should really not be priviledged to or interested in unless there was an understanding between them. I see now that your speculation does not coincide with your understanding of Darcy's character or propriety any more than it coincides with mine. So it is yet another reason to suspect that Darcy would have no way of knowing that Collin's exaggerated Lizzy's illness. That is, if he did. I don't think it is beyond the scope of Collins' character to exaggerate in order to avoid Lady C.'s censure.
