Sam and the team went into hiding after they are done with the assassins and the manager.
He held a meeting with the team to decide on their next step. The team is divided into two opinions. One of that since they knew the location of one of the pieces of the heirloom. The father of the current manager has one so they wanted to take advantage of the incident and directly attack them by surprise.
As for the second opinion, they wanted to wait here. Since there is a possibility that another party might know that his son died, he will definitely take some action and send some people here, in fact, he might even come here directly, so they wanted to lure him out and deal with him slowly.
Both of them have their own advantages, but Sam leaned mostly towards the second plan, but since he let his team members decide what to do he didn't interfere and just went to take the rest.
