Although the episode in question is No. 701, there is a very real possibility that it will not feature as the premiere. NCIS: LA shot two season 7 episodes during May, one that featured NCIS's Tony DiNozzo (Michael Weatherly) and one that was directed by Chris O'Donnell (Callen), the former of which could easily function as the premiere.

Regardless of how it begins, season 7 will treat viewers to more enticing Callen reveals. The orphaned agent has spent his life trying to unravel his past, and the events of "Chernoff, K" has placed the truth almost within his grasp.
