Since he entered that prison he knew that something could go wrong, but it didn't matter if it was for the mission.

He needed the help of a criminal and that was you... you could help him steal the Bow of Ra' that Black Mask asked him for and that's why he went to Belle Reve Penitentiary

"You're going to help me and it's not a question" He said as soon as He approached your cell because he really didn't like being in that place.
