Narrative

PRIOR TO ENG START; PROC REQUIRES SECURING THE COCKPIT DOOR. THIS PROC WAS FOLLOWED AND THE DOOR INDICATED 'LOCKED.' AFTER DEP; AND DURING CLBOUT; THE FLT ATTENDANT CALLED THE FLT DECK. THE CAPT ANSWERED; AND AFTER A BRIEF CONVERSATION WITH HER; HE INSTRUCTED ME TO LEVEL THE ACFT AND PREPARE TO RETURN TO NASHVILLE DUE TO A DISTURBANCE IN THE PAX COMPARTMENT. DURING THE DSCNT; THE CAPT ASSUMED CTL OF THE ACFT. AS WE WERE NEARING NASHVILLE; THE FLT ATTENDANT CALLED THE FLT DECK TO ASK IF WE WERE LNDG. I REPLIED THAT WE WERE. THE CAPT TOOK THIS OPPORTUNITY TO GET ADDITIONAL INFO AS TO THE SIT IN THE CABIN. SHE ADVISED HIM THAT THE ONLY PROB WAS THE COCKPIT DOOR WAS OPEN. THE DOOR WAS THEN SECURED AND THE FLT CONTINUED TO ITS ORIGINAL DEST. APPARENTLY; IN HER INITIAL RPT TO THE CAPT; THE FLT ATTENDANT HAD SIMPLY STATED 'TURN AROUND.' HER INTENT WAS FOR THE CAPT TO SEE THE OPEN DOOR; BUT THE CAPT PERCEIVED HER COMMENT TO MEAN THAT THE FLT WAS IN JEOPARDY AND THE ACFT SHOULD BE TURNED AROUND AND RETURNED TO NASHVILLE.
