Any updates?

Have we heard anything recently about this? After watching the last episode of Prison Break I got the impression they were setting up for a spin off with Gretchin trying to escape, plus why would someone like her let Sarah escape when she could have easily got her caught too, like we are suppose to warm to the character a little. Also why use someone like Lori Petty for such a small role unless it was going to pop up somewhere else later on.

Anyone know anything to stop my brain working over time? lol
