It could be his power that they did not talk about. Or, it could be that they were so limited in time, so, the initial thought was that she was late. Then, when they were close to the end, and there was no enough time to explain the details. She checks her watch and she's not late. I get it, it raises so many questions on what happened their exactly. But, the movie overall was nice. At least, you have to give it that XD.
