Top of The Building

Jack made sure to always go in his old building to check the surroundings where he should be able to plant the bomb he was planning to put.

How he could possibly get in and get out of the building at the right time of planting the bomb and the how many minutes before he could get out of the building.

He's been busy doing it every day since he was started creating those bombs. He made sure that his plan will work out this time because he really need to get that item in his office. So his been going back and forth to his old office building to check it's neighboring building and its surroundings.

He always went there in the morning for it is more safe if there is sunlight and then after his thorough check he will go back to his lab to complete his project. He's been up for a constant night and sleep and just goes to bed at dawn.
