What's going to happen in Prison Break Season 4?

I'm so pumped for the fourth season of Prison Break especially because Sara is confirmed to be returning! I'm guessing that Mahone, Whistler and Gretchen realise that they are missing important information from the book and try to work out where it is. T-Bag blackmails them into doing another prison break for it, and Bellick finds out (as usual). Things get complicated when Michael and Lincoln (finds out his brother is in trouble) corners Gretchen, who plays her last chip in revealing that Sara isn't dead yet. Lincoln and Sofia have now obviously hooked up, and he tells her to look after LJ. They both come to the rescue mid way through the season to bail the brothers out. Sucre also finds out something important (steals the book) and gets to call the shots over the Gretchen and the company. I'm also tipping Kellerman to make a surprise return and aid Sara in escaping from the company! Best answer to the most interesting plot you guys come up with!

I can't help myself I must continue my plot! That Jason Lief guy is another Fibonacci and has incriminating data against the company. Whistler was tailing him trying to kill him when he got lured into a trap in Panama. The "co-ordinates" are actually a code for where Lief is, and it becomes a race to the book for both Michael and the company. Sucre and T-Bag meanwhile are at blows, and T-Bag doesn't want to bring back the chicken foot tradition of Sona because he'll get owned by Sucre. Feuding at the prison gets surprisingly settled by Bellick when he comes up with a weird solution (haven't thought about it yet). Kellerman saves Sara and it's a weird mini plot between them, because he tried to kill her and is now saving her life. They go on the run and try to rendezvous with Michael. The escape from Sona failed and the company now need Michael to break out of Sona again! Things change, as corruption at Sona forces the place to close down. The inmates are moved to a new prison.

Thats pretty cool....just one giant statement....I did hear that all of the characters are going to be involved in bringing down the company.
