In the NCIS Season 20 finale, Wilmer Valderrama's character Nick Torres has a new look with a shaved head and is shown in prison. The episode is titled "Black Sky" and will end with a cliffhanger that will lead into Season 21. It's unclear what situation Torres is in, but it's assumed he's undercover. Fans are left to wonder how he'll cope and if he'll need help from Dr. Grace Confalone (Laura San Giacomo). The previous season ended with Parker being framed for murder and Gibbs' boat exploding, among other cliffhangers throughout the series.
