I really don't understand the complaints about the TL and the watermarks. I've seen true Chinese-translation MTL garbage fire that is nigh unreadable even by the fastest of skim-readers, and I've seen watermarks that are right in the middle of every page of the entire comic. The result we've seen here is mild at best.
I feel like ya'll are used to really high quality scans if this sort of thing bothers you.
EDIT: I get the feeling that maybe they reuploaded the chapter. I can't tell via the timestamps, but the watermark isn't even on every single page. Only on 2-3. Or maybe ya'll really are grumpy, iuno.
Anyway,
I thought that the merchant was actually Light in disguise, considering in the prev chapters, their plan was to have the dwarf ruin himself, and have his own country fuck him over. But it does make sense that it might be his brother as well.
