The moment the bear-masked one saw Ethan, he knew that his suspicion was right. This world belonged to that novel that he read back when things were normal.
He was a kid at that time so his memories are a bit vague, however, the moment his eyes landed on Richard and Emily, he knew that this indeed was that book which wasn't that famous even when it was at its peak.
Ether, Aembr, Ambrobates…these terms were familiar to him. Although he didn't read until the end, Ben knew that this character, known as Richard, was supposed to be dead.
However, considering a resident from Earth has been reborn as the novel character, it doesn't remain surprising that Richard was able to survive.
Not only that, he has somehow shifted the plot so that Emily is on his side, as well as the Protagonist.
Ben has been holding back his curiosity since last night. He didn't even tell Carl about it.
