My opinion of what Lulu will do is the same as yours. He will surely prioritize his imprtant person over others (especially Nunally . . .I think even Suzaku and the others as well) but he'll still guilty for not saving the life of an innocent person. The Lulu right now is still a moral person.
With Suzaku though . . .I can't tell. With his sense of morality, he would highly prefer to save both parties no matter what. It's highly possible for him to save his important person but it's also highly possible for him to save the innocent one instead. He's hard to predict x_X But whichever he saves, for sure he'll have full of guilt and regrets for the rest of his life. But I see him continue to live normally (whichever he chooses) but has not completely forgotten the past (e.g. if he saved his important person, that person will help him recover from regrets; if not, he will recover by thinking that his important person wouldn't want him to live like that . . . or anything else close to that ^^;)
