Due to either a glitch or development oversight, if Shepard has one person 'locked in' and are at the 'challenge' stage with any of the other possible subjects prior to entering the Omega 4 Relay, Shepard has the option of dumping the 'locked in' subject after completing the finale, provided that Shepard survives. Doing so will allow Shepard to court one of the other subjects and the intimate scene normally seen before proceeding through the Omega 4 Relay will instead play as soon as the dialogue ends. It is thus possible to experience all three partners and their respective scenes this way. However, once a partner is 'dumped', they cannot be courted again. It is currently unknown how this will affect your save game and therefore affect the events of Mass Effect 3.
