I Can Explain

After leaving the Lancaster's mansion, Leon headed to check on the Golden Lion Gang in the new Lower West District. He wondered if they had reverted to their old ways and up to no good during his absence.

The Golden Lion Gang's headquarters was one of the buildings that took priority during the reconstruction project. Not only was it one of the first buildings to be completed, but it was also opened for business. 

This was an amazing feat to accomplish in such little time. The building was not very tall, having only three floors, but it was very wide and capable of housing over two hundred people. 

Considering that he left the wealth of the Four Great Families in their hands to manage, even if the Golden Lion Gang did not open for business, it would still be enough to support the Golden Lion Gang for a lifetime.
