In Season 3 Episode 10 of Prison Break, Sammy gets submerged and killed by the terrain, which just drops on him after he tries to escape through the tunnel created by Michael. Soon after that each of his body guards get killed and Lechero is back as the chief of Sona.
In Season 3 Episode 11, at the beginning, Lechero says the following
I don't care who knows what, as long as somebody knows how the .... we get out of here by tomorrow.
Now I understand that nobody wants to stay in jail, so I suppose everyone, having the possibility to, would decide to escape rather than staying behind the bars. The question is: why is he in a hurry? He is back as the chief of the jail and I was wandering what was the reason, which was pressuring him.
I thought an explanation would have been, that the collapse caused a hole in the "no man's land", but as we saw, they all checked if there was one, after it happened and there wasn't. So this is not a reason to stress Lechero.
Then of course the hole appears, because the rain comes, providing a reason to hurry, but then again Lechero told Michael, he is the one who has a deadline, so the whole story makes me a little confused.
