In the WN, they were much nastier and unrepentant, so Rein decided to turn them in and forget they existed(lol), and eventually, after this whole thing with the merchant is resolved, we learn the guild revoked their licenses when he visits the guild and overhears them arguing with the staff. They also try to beg Rein for forgiveness and offer to pay him to cover it up as he's leaving, but he doesn't want to give them the time of day. One thing that got cut here from both the WN and LN is Rein being most angry at them because their bullshit could've led to the poachers escaping and bringing danger to the hornwolves. That was pretty cute and very Rein-like, so I'm sad to see it go.
