Prison Break WEEK 2

I have to star again the serie "Prison break" (I had stopped following this series because I have by error watch the last episode of the last series ... So I know all answer to all question, I am self spoiler, it's so bad).
So in the first episode, the principal person (Michael Scofield) Is tattooed (we know what in the next episode).
M.S organise an robbery for go to prison for to join his brother and get him out...
In my opinion M.S is an very intelligent person which hides many secrets!
