Zain couldn't speak about his plan openly inside, there were too many that would listen in and suspect something else was happening, at the same time, he didn't want to make a big deal out of something that possibly could be nothing, but based on the System he didn't think that was the case.
Zain was quite aware of his popularity inside the Reborn group, there were many that found great confidence in his strength and quick leadership while out on missions. So much so that if he was to leave the Reborn group and asked others to come with him, a little more than a few perhaps would take up on that offer.
Which was why he needed to investigate on his own, as he didn't want there to be any infighting, at least not until he learned the truth.
Currently, all six of them were waiting out in an office building on the same street as the Reborn group, they were keeping an eye out at a diagonal angle across the street, seeing who entered and left.
