Where have you been thelast1??? Ever since about a month after the game came out people have been debating this. But alas, of course you cant bring her back. If you think logically, you could talk to every person and go every where in the game space by space and never find a way. Youd waste just as much time doing this as you would experimenting with all the rumors people have made up

EDIT*

I lie, go buy yourself a gameshark and you can play with Aeries and Seph on your team. I forgot about that. But the game freezes up in some scenes
