Hereโs a smoother and more engaging rewrite of your passage:
Things have been tense on NCIS since its midseason return, especially for Jessica Knight (Katrina Law), who was blindsided by the revelation that Nick Torres (Wilmer Valderrama) is dating her sister, Robin (Lilan Bowden). What stings even more? He never bothered to tell her. Knight insists her frustration isnโt just about the secrecyโitโs about the inevitable fallout. She knows her sister well enough to predict a messy breakup, and she dreads the day sheโll be forced to choose between her sibling and her partner.
So when Nick starts dragging himself into work, clearly exhausted, Knight assumes itโs from late nights with Robin and gives him a hard time about it. But she soon learns the truthโhis sleepless nights have nothing to do with romance. Instead, heโs deep undercover, working to infiltrate a dangerous criminal gang.
Nick successfully gains the gangโs trust, but his cover is nearly blown during a check-in with Knight. Thinking fast, she spins a lie to save him, claiming that โDonnyโโhis undercover aliasโis actually her fiancรฉ. The quick thinking buys him some time, but it also gives Parker (Gary Cole) an idea: Why not stage a fake wedding as the perfect setup to take down the gangโs leader?
NCIS Director Leon Vance (Rocky Carroll) is understandably skeptical. โYou want to do what?!โ he exclaims when Parker presents the plan.
But Parker insists they go all inโif theyโre going to pull this off, it has to be convincing. That means flowers, a cake, a wedding dress, music, food, and drinks. And who better to handle the details than Robin, who, with five engagements under her belt, is practically a professional at planning weddingsโincluding, now, her sisterโs fake oneโฆ to her boyfriend.
