After spending some time apart in past episodes, Maggie (Missy Peregrym) and OA (Zeeko Zaki) are back together when FBI returns on Tuesday, April 1. "We spend a few episodes disconnected from each other with the episodes off . . . . So our reunion is very high stakes, and it’s going to be really fun to get to give that moment to the audience when it comes," series star Zeeko Zaki told TV Insider of the duo's reunion. This happens in FBI Season 7, Episode 16, "Covered," when Maggie goes undercover with OA's support, but the operation goes south. CBS released a sneak peek of the episode airing on the first day of next month, previewing the operation and a possible devastating outcome.
