It’s the first scenario and Dokja and the people left in his train cart had escaped, all but him getting across the bride, only even numbers allowed over. Joonghyuk walks out and sees Dokja, not recognise him. The two to get into an argument, Joonghyuk drags Dokja over the bridge, now dangling him by his shirt off the side. That’s when they see you and one other person crossing the bridge. Dokja doesn’t recognise you from the novel and Joonghyuk doesn’t remember you from his past regressions.
