Nothing ever went as planned.
It was the curse that had been looming over Rex ever since his climb to power started.
Regardless of how careful and meticulous he planned out a situation, there will always be variables that would mess up his plan or at least be an obstacle to success. It happened so many times that Rex was already used to it.
His success always relies on how he reacts to the developing situation.
It had always been the case.
Due to that, he didn't feel relieved when he managed to force Haxel to help handle the situation.
That was only the beginning, and there's bound to be more problems he needs to deal with.
Haxel was extremely confident, so Rex had to keep an eye on his next moves.
Regardless of what his plan was, Rex knew that he had to somehow go through the powerful bubble first, and that filtered out a lot of unnecessary clues that would lead nowhere. All Rex had to pay attention to was anything that could possibly shatter the bubble.
