Less commonly, a trap can refer to when the Force is with someone, but they are not a Jedi yet, and a second party wishes for one to join him, and together they can rule the galaxy as father and son. This type is generally announced by one's unknown sister as she is taken away by a bounty hunter. In addition, a trap can also refer to when one senses Count Dooku, to which the other replies, "I sense a trap." In these cases, the next move is to spring the trap. These two types are becoming increasingly rare, subsiding to the first type mentioned.
