Numerous officers were often referred to as commanders, or wore commander's rank insignia, but were actually other ranks. In TNG: "The Best of Both Worlds", Jean-Luc Picard remembers meeting Lieutenant Commander Riker, but Riker was wearing commander's insignia in the corresponding scene in TNG: "Encounter at Farpoint". This happened in TOS also, as Spock was referred to as an lieutenant commander in TOS: "Court Martial" even though he regularly wore commander's stripes up to and including that point. The same went for Benjamin Finney in that episode and Giotto in TOS: "The Devil in the Dark", both of whom wore commander's insignia but were clearly referred to as lieutenant commander in dialogue. The reverse happened to Chakotay, who wore lieutenant commander's insignia but was only referred to as commander for VOY's entire run.
