Commentary:
If you're wondering what Lopu is talking about in the first panel, he was about to bring up the twins. Lopu has been told about Lubo's fight in the forest last night. Which is why he went "Hmm..." in the first panel on page 13.
Oh hey there's Gibson again. And just like that there he go. Nothing much else to say about him I suppose.
