Did you see whether 2B really had a boarding pass for 2B? It could have been a seat poacher who was assigned to 3C for example and just decided that he/she preferred 2B. It also sounds like the FA was confident that 3C was unassigned (to someone who would claim it), so your poacher could have moved with the complicity of the FA.
