The next big question in 11 Minutes Ago is why, having made two trips and obtained the air sample, Pack returns again. The smaller question is why he returns to 8:00 instead of 8:15.
We find the answer to the larger question in the previous resolution. In his original trip to 8:30 he recognized the necessity of impressing upon the film crew the necessity of persuading his younger self, due to arrive at 8:45, of the necessity of returning, but he did so with very minimal information which they did not necessarily convey terribly well. Thus the message that he got on his 8:45 trip from June 2050 was that it was absolutely necessary that he return, which indeed he did on his 8:30 arrival from December 2050. Yet since he got the sample on the 8:45 trip he does not understand why he has to be there at 8:30 (he succeeds in running interference for himself, but does not recognize what he has done), so when he insists that the film crew must persuade him to return he gives them even less information, less reason for him to do so, so the message he gets is only that it is very important that he return–an importance he will never understand, because he will never recognize that he would not have gotten the sample on the first trip without the second, and as events unfold he will create a new reason.
However, we once again have events that cannot happen as we see them because he has not yet done what must be done to make them happen. In this case, he spends his eleven minutes which we see trying to find Cynthia, only to have her find him in the last seconds and invite him to join her in the closet in five minutes. Yet the first time he makes this trip, she has never met him; and indeed, it is doubtful whether he has met her–she certainly did not kiss him in the 8:45 block, and she did not talk to him about his question which he has not yet considered asking in the 8:30 block. Once again, nothing we see in the 8:00 block can be what happened on the original trip from March, 2051.
The one thing that does happen in this block is it is announced that they will be tossing the bouquet in fifteen minutes, and Pack realizes he arrived at the wrong time. He had intended to work backwards in fifteen minute increments, undoubtedly searching for the reason he was so adamant that he return, and he missed the 8:15 block. There is not yet a drawing to which he can refer, but he will wonder why he missed it.
It is also likely that he will begin asking about the party guests. There was some reason his self wanted him to return to this party, and he has not yet found it, but it is at least possible that it lies in the identities of the people. He will collect names, learning what he can about anyone he can identify. What he can remember he can expand by searching the Internet in the future.
The relationship between Pack Eoling and Cynthia Valco is a predestination paradox. He becomes interested in her because at 8:45 she kisses him and at 8:30 talks to him about how relaxed she is because at 8:15 they had their tryst and she is basking in the afterglow. They had that tryst because from the moment of his arrival at 7:00 he has been pressing to get her to fall for him and by 8:00 had her enchanted enough that she found the place. They would not have had the 8:15 tryst had he not worked to win her heart from the beginning; he would not have worked to win her heart had she not fallen into his arms at the end. It is an uncaused cause, and we seek the original cause. It probably starts here. In trying to understand why it was so important for him to return, he researches Cynthia Valco, discovering a girl worth getting to know better–graduate school graduate, bright, efficient, yet caring, always putting her friends ahead of herself, single with few past relationships, and friends who hope she will find the right guy.
Something in whatever he learns must pique his interest in her; he begins trying to talk to her. He is not, at first, trying to get her to fall in love with him, because he does not know that that will or even can happen. He is only trying to meet this fascinating girl and discover whether what he read is true.
We are getting ahead of ourselves. He has more trips to make.
