A custom-made anesthetic gas released in a Quantico marine base high school and former arsenal's ventilation system made substitute English teacher Walter Carmichael's class faint, allowing the abduction of Navy brat pupil Rebecca Mason (13). During parents Navy officers Nick Jr. and Lisa's Persian Gulf tour, she stayed with doting and adored grandpa Nicolas Mason. He tricks the team so he can handle the ransom claimers himself, bloodily, apparently twice, but fails to get Becca. One of NCIS's internship kids helps Abby trace the gas to a pharmacy, which proves a cover for Nicholas's top-secret past. Written by
