The group decided to split up and ride in a different vehicle as to not get attention from the reporters when they arrive at the funeral parlor.
Daniel and Andrea went ahead of them with his secret service, followed by Prince Alexander, Alexa in another vehicle. Chrissy and Sophia, along with the remaining of their entourage, rode in the same car.
They knew that there would be many reporters at the wake. Therefore they need to be inconspicuous. If the reporters see them arriving in one car, a question might arise, and they are not ready to answer any question in regards to their relationship.
The vehicle where Daniel and Andrea were riding arrived first, everyone knew the couple, and they did not bother them and let them pass without bombarding with a question. They only took pictures and made their own story to tell the masses.
