So Grizel decided eagerly, and she was on the point of telling him how proud she was of his book, when Tommy, who had thus far behaved so well, of a sudden went to pieces.
He and Grizel were together.

Elspeth was a little in front of them, walking with a gentleman who still wondered what they meant by saying that they had heard his baby cry.

"For he's no here," Corp had said earnestly to them all; "though I'm awid for the time to come when I'll be able to bring him to the Den and let him see the Jacobites' Lair." There was nothing startling in this remark, so far as Grizel could discover; but she saw that it had an immediate and incomprehensible effect on Tommy.

First, he blundered in his talk as if he was thinking deeply of something else; then his face shone as it had been wont to light up in his boyhood when he was suddenly enraptured with himself; and lastly, down his cheek and into his beard there stole a tear of agony.

Obviously, Tommy was in deep woe for somebody or something.
It was a chance for a true lady to show that womanly sympathy of which such exquisite things are said in the first work of T.Sandys: but it merely infuriated Grizel, who knew that Tommy did not feel nearly so deeply as she this return to the Den, and, therefore, what was he in such distress about?
It was silly sentiment of some sort, she was sure of that.
