Which sentence in this excerpt from Mark Twain’s The Adventures of Tom Sawyer shows that Tom and Huck are both afraid of Joe?

Tom was a glittering hero once more—the pet of the old, the envy of the young. His name even went into immortal print, for the village paper magnified him. There were some that believed he would be President, yet, if he escaped hanging.

As usual, the fickle, unreasoning world took Muff Potter to its bosom and fondled him as lavishly as it had abused him before. But that sort of conduct is to the world's credit; therefore it is not well to find fault with it.

Tom's days were days of splendor and exultation to him, but his nights were seasons of horror. Injun Joe infested all his dreams, and always with doom in his eye. Hardly any temptation could persuade the boy to stir abroad after nightfall. Poor Huck was in the same state of wretchedness and terror, for Tom had told the whole story to the lawyer the night before the great day of the trial, and Huck was sore afraid that his share in the business might leak out, yet, notwithstanding Injun Joe's flight had saved him the suffering of testifying in court. The poor fellow had got the attorney to promise secrecy, but what of that? Since Tom's harassed conscience had managed to drive him to the lawyer's house by night and wring a dread tale from lips that had been sealed with the dismalest and most formidable of oaths, Huck's confidence in the human race was wellnigh obliterated.
