There are times when you definitely want to get your own client witness off of the stand, let them recuperate and go back on to rehabilitate their testimony.  It is unusual to have a witness testify as an adverse witness and his own counsel pass without asking a single question. 

In a case against a homebuilder, the regional vice president was on the stand as a hostile adverse witness.  After cross-examination, he was visibly disturbed, probably because he knew that he personally was involved in the fraud on my homeowner clients.  It was exactly because of that that I expected he would be rehabilitated through direct examination by his counsel.  No chance. 

Once I passed the witness, his counsel immediately stated "No Questions." and the vice president jumped out of the witness chair and went straight to the door out of the courtroom.  It was unusual and abrupt and even more surprising, they never brought him back during their defense of the case. 

I was so perplexed by this that I assumed there was some kind of dirt on him that I had overlooked.  After winning the case, I went back and checked public records just to make sure and never found anything.
