It appears NCIS: Los Angeles has developed quite an amicable relationship with the DEA.

Much to Deeks' (Eric Christian Olsen) chagrin, DEA Agent Talia Del Campo will rejoin the OSP in "The Long Goodbye." Mercedes Mason's character quickly became a fan favorite after her introduction in season 5 and viewers will get a second helping of the kickass character before season 7's midseason hiatus.

The reasons behind Talia's return are currently unknown, but it appears the reunion may have something to do with a new character by the name of Jada (Ella A. Thomas). Whatever Hetty's (Linda Hunt) team is up to, it will involve bikinis for the ladies.

Poor Deeks. His little heart might not be able to handle Talia’s merciless flirting right in front of a scantly clad Kensi (Daniela Ruah).

Penned by Dave Kalstein (“Citadel,” “Expiration Date”) and directed by executive producer John Peter Kousakis (“Active Measures,” “Chernoff, K.”), “The Long Goodbye” is filming as episode 8 but will air as either episode 9 or 10. In the meantime, Callen (Chris O’Donnell) and Co. will have their work cut out for them when NCIS’s Tony DiNozzo (Michael Weatherly) drops by in “Blame it on Rio” (see video below).

NCIS: LA airs Mondays at 10 p.m. ET on CBS.
