I really had to stop at this scene. The amount of information they know is weird. They got to know about the incident because they were present when Reiji and his mother were informed. And they even know Marco was hurt although it wasn’t an Action Field (which leads to the Dark Duelist being most likely the culprit).
But:The LDS conceals the fact that Marco went missing, which we can deduce from this scene. So how do they know anything at all except for the fact that something happened to Professor Marco? And how do they know about the way he got hurt? It is really bugging me…
