Additionally, there are also some mild speculation spoilers not related to the above interview
Spoke to Prison Break brothers Wentworth Miller and Dominic Purcell. One PB spy tells me that there's going to be a crisis between the two siblings next season that extends beyond Michael's imprisonment. What could cause such a rift? Maybe Lincoln and Sara will fall for each other while Michael's behind bars? "I don't know what's going on with Sara," Purcell shrugged.
Hmm...that's not a confirmation, but it's not really a denial either.
I'd ask her myself but I don't see Sarah Wayne Callies at the party tonight. Maybe she's filming back in Texas. Miller said he was catching a plane soon to head back there.
