Unexpected Quest

A group of friends were having a full swing party celebration while waiting for another friend to arrive, no one saw or notice anything unusual While the camera person film his fellows within the circle the camera captured one guest covered with red that sat toward the door on the video, a young man who appears to be just another guest enjoying the party with his red face. Is he a ghost? Or another friend messing around?
During the party no one saw or noticed that unexpected red face quest was there until the group viewed the video. The creepy part is that the unexpected quest was actually their friend who they were waiting that night. Unfortunately, that friend of their had a fatal accident on his way to the party and died. Some how his spirit came and enjoy the party with them.
