The next scene

While Leon was breaking down his living hall, at the other end of the city, Nikun got his sister, Shea safe and sound.

Nikun wasn't waiting in the Highland club as Shea had thought. Shawn had increased security at Highland club to make sure none of the customers will be affected by anything. Meantime Aaron's team was keeping an eye on Wade Merton's movements. 

Nikun had asked Shea to get ready only when they confirmed Wade had fallen in their trap and was waiting for Shea at the hotel instead of Highland.

Hence, they were aware from the very beginning about Wade following Shea. They weren't sure if Wade had plans to follow her till Highland or had plans to attack in between.

At least one thing was sure, Shea's life wasn't in danger, they wanted her alive to threaten the Morris family.

Nikun was in the private car with the deputy chief of police who was there to witness everything live and catch Wade Merton and his team redhanded.
