Other than Stuart, the three people pursed their lips as soon as they heard Valerie ask them about Charles. It was not that they did not want to comment about this matter to them. But the problem was that they did not know how to disclose the truth to them when it would only bring more problems to them in return.
But they had no choice either. They had to have someone from the Intelligence, someone who held authority and command as their support, and Valerie was the best choice they had. Keeping things a secret from her when all they wanted was her help was not what they had in mind. It would only ruin their plans.
So, eventually, they decided to pull Valerie and Preston into their plans, and just like that, Stuart too entered their group without any knowledge of what was happening around him.
