Lucas became kind of scared as David beckoned for him to come closer. He knew there must be a reason for him to say that and it could not be good from the way he analyzed it.
"Sir, I'm sorry about the question, I just wanted to be sure what the mission was so that there would be no room for mess-ups. Please, boss." Lucas pleaded with David as he hesitated from going closer to him, knowing the outcome might be fatal.
David looked at him for a moment as he tried to subdue the anger rising inside of him. He had actually wanted to do something fatal to Lucas for daring to question him and asking for him to repeat himself.
He then calmed his nerves as he thought that Lucas did make a bit of sense of what he asked. He should actually be sure of the mission and the order given because he could not give room for failure from them.
