Shigure: Gets 3 days, but he's probably only using one or two. He's going to get pushed out the barrier by Abel and then he'll go check on things, give Mitchan some manuscripts and see what godawful remodeling Akiha and the first Haruhi did to his house.
He'll come back and get slapped by Akito, probably.
Hughes: Gets one day and is going to Destiny Islands (THANKS KAIRI) he''ll be all over the place and decide if he wants to move there with his family in the future |D
Peter: Will check on his mom and make sure the world isn't a mess. Aaand I still haven't decided if he'll be coming back from it.
AS FOR THE DROPS:
Spike will kill people and get in trouble and then spend the rest of the time with Dru. He won't be returning to camp from it.
Alec: Will arrive to the Vatican with Brother Petros and hug his Sister and probably cry a little, he'll stay there.
Nill: Will hug Bishop and Naoto and then she'll learn how to read and write and will send letters to Haine and Badou for Christmas.
And Muraki and Fon haven't been in camp for a year yet.
