Using the power of shadow he instantly came behind those people. But he did not do anything to them. Right now he was interested to know the motive of those people so he just silently stands there. Unfortunately, none of them said anything so he was not able to hear anything from them.
Right now the person who was at the front directly signals everyone to separate their way. Actually, before using the shadow technique, Alex created a clone in that place so right now everyone is still thinking that Alex was present in that place. So the leader quickly signals everyone to attack that clone Alex from various directions.
None of them said anything and just nodded. Wasting no time they quickly went separate ways. Still, now nobody realized that one more person was to decide them and after those people went separate ways, Alex decided to follow that leader.
