What was it?

"I am serious," said Estella, not so much with a frown (for her
brow was smooth) as with a darkening of her face; "if we are to be
thrown much together, you had better believe it at once. No!"
imperiously stopping me as I opened my lips. "I have not bestowed
my tenderness anywhere. I have never had any such thing."

In another moment we were in the brewery so long disused, and she
pointed to the high gallery where I had seen her going out on that
same first day, and told me she remembered to have been up there,
and to have seen me standing scared below. As my eyes followed her
white hand, again the same dim suggestion that I could not possibly
grasp, crossed me. My involuntary start occasioned her to lay her
hand upon my arm. Instantly the ghost passed once more, and was
gone.

What was it?

"What is the matter?" asked Estella. "Are you scared again?"

"I should be, if I believed what you said just now," I replied, to
turn it off.

"Then you don't? Very well. It is said, at any rate. Miss Havisham
will soon be expecting you at your old post, though I think that
might be laid aside now, with other old belongings. Let us make one
more round of the garden, and then go in. Come! You shall not shed
tears for my cruelty to-day; you shall be my Page, and give me your
shoulder."
