NCIS: Los Angeles Season 11 Episode 4 seemed like an effort to clean up a barely dangling storyline.
Callen and Sam found themselves back on board the USS Allegiance, under the guise of accompanying Ehsan Navid, last seen on NCIS: Los Angeles Season 5 Episode 14 and expected never to be seen again.
But no, Ehsan has repaid Callen and Sam's earlier kindness by becoming an NCIS agent. He was now appointed as the agent afloat for the Allegiance, replacing Brian Lee, killed on NCIS: Los Angeles Season 10 Episode 23.
Callen and Sam came along to help Ehsan with the transition to his new post.
Of course, nothing is ever that simple.
Harmon Rabb of Jag fame, the Allegiance's X-o, wasn't around because, well, that ship has sailed.
