1. Remember Thapa?
The NCIS: LA team last worked with Jemadar Thapa in Season Five's "The Frozen Lake" to recover a stolen USB drive containing plans to steal Pakistan's nuclear arsenal. Thapa double-crossed the team intending to bring the drive back home to India, but ended up getting captured by the Armenian mob after trying to procure a fake passport. Deeks, having previously worked undercover with this mob in the past, went back under as a lawyer to rescue Thapa and recover the drive.
