As usual, Sarah only came far after the event had started. The mansion was already filled with guests when she arrived, spreading around the estate with their own groups while waiting for a chance to talk to the chairman.
Even if only a handful of selected people got invited, they came with their families or a plus one, so even the garden of the front yard was filled with people, especially the children who got bored inside. Some of these children would probably end up following their parents and working for HS in the future, so they were brought to this boring party instead of visiting their grandparents or enjoying their winter break.
That would be the case anyway, if HS Group were still around in the future.
