Heaven often overlooked many things in the past, using her own logic to make sense of them. However, with Dragon in the picture, she wanted to ensure the true allegiance of everyone around her. Not that she trusted Tiger with all her heart and soul. The only people Heaven trusted now were herself and Dominic. Therefore, Tiger wasn't the only person she asked for the same favor. She asked every single one of them.
This might be considered as breaking her team apart, but it could also be seen as the opposite. She was planting the idea so that if someone turned out to be a mole, they could deal with this mole properly. If no one did, then that was good. As for Dane Zhang, Heaven wanted to make sure this man was loyal to Dominic.
