So I must say, I'm honestly surprised at the lack of anticipation for what will come of Serah in Lightning Returns. Having just completed XIII-2 and the Requiem of the Goddess DLC, I noticed some things that really make me curious to see what the future of Lightning's sister will be. We know that Noel is in Lightning Returns, and logic would tell us that he probably has some connection to Serah, but to what extent remains unclear. We haven't seen anything of Snow yet in LR previews, nor was he there in XIII-2 Academia 500AF so far as we know. Will he be back on the search now and run into more personality conflicts with Noel? Will Serah and Snow ever get married, or will Noel become something of a romantic interest and break that party up before it starts?
But all that is assuming Serah is still alive and well,
Of course, there is this Lumina character we've seen a bit of. So far all we know for sure about her is that she is a new character, but SE called the similarities in appearance "mysterious." I wonder: all through XIII-2 we were told that Serah and Yeul were the same. Mainly all we saw this to mean was that Serah could see the future. But Yeul was a bit more than that...she was periodically reborn. Could it be that Serah comes back like Yeul did, and if so, would she have to die every time she reached a certain young age? Lumina certainly looks like a younger Serah...

despite being dead. I don't think any of us accepted Serah's death in XIII-2 as being final, and I'm pretty sure Lightning didn't, either. That was one of her stated reasons for becoming a crystal: so she might be able to "guide Serah's soul" in the future, and have just one more time for them to laugh together.
