What does 2 Samuel 18:29 mean?

The king asked, 'Is the young man Absalom okay?' Ahimaaz answered, 'When Joab sent your servant, I saw a lot of confusion, but I don't know what happened.' 2 Samuel 18:29 - Modern Text Bible

(David's first concern is for Absalom, not the victory. Ahimaaz avoids telling him the painful truth.)
