Explosions have rocked NCIS: Los Angeles as of late and the Special Operations team will be jolted by another blast during "Exposure."

When a bomb interrupts a military charity event, a ZNN reporter will claim to know just which terrorist group is behind it. Callen (Chris O'Donnell) and his crew will have to look into Dana Steele's (Tiffany Dupont) accusations and apprehend the culprits before they strike LA for a second time.

Penned by Joseph C. Wilson ("Between the Lines," "Fallout") and Jordana Lewis Jaffe ("Iron Courtain Rising," Big Brother"), the season's penultimate episode will feature guest roles from Dupont ("Greek") and Tony Okungbowa ("Mother of George") while also bringing back an unlikely partnership.

Densi Drama Spills Over Into Premiere [PHOTO]? Who Is Kensi Bonding With?

"Another Nanger day," tweeted Miguel Ferrer (Granger) as he paired up with Nell (Renee Felice Smith) for filming in late March. "A guaranteed ratings bonanza."

With Kensi (Daniela Ruah) back from Afghanistan, you would think Nell would be confined to Ops once more. Instead, the brilliant analyst entered the field alongside Granger in "One More Chance," and it looks like their partnership could help keep Nell in the thick of the action without having to interrupt other agent's well-established dynamics.

Are you excited to see Nell in the field again? Who should she partner with? Tell us what you think in the poll below!
