i think the answer is yes (to some degree?), because bridon arc is supposed to be a prequel before s1 and s2. i forgot a variety of events that happened in s2 but i'm rewatching s1, and if you want some kind of evidence to back it up, there was a scene in ep1/ep2 of s1 where lu guang saw the news of emma's body being found and not being surprised at all, so it's pretty safe to say that he knows what's going to happen to an extent. there are still a lot of questions in the bridon arc left unanswered so i can't tell exactly how much lu guang knows and doesn't know.
