'The Rookie's Lisseth Chavez Promises This Isn't the End for Celina and John in Season 7

Celina Juarez (Lisseth Chavez) and John Nolan (Nathan Fillion) have been inseparable for sometime on the hit ABC drama series, The Rookie. Much of that stems from the fact that Celina was a rookie and John, her training officer. Having been trained by others who came before him, now Nolan has passed on his wealth of knowledge and experience, and Celina is all set to launch out as a newly-promoted P2. Now free of the shackles of being under probation, Celina is eligible for non-specialized assignments without John's oversight. It means their relationship has evolved, and Chavez has recently commented on it.
