Someone has probably brought this up, so I apologize if I am repeating anything, but I am a little concerned with what's going to happen next. See, I just started reading the comic a few weeks ago (curse my fiance for telling me about this comic.
Now I have something else I am addicted to reading) and took the following comics into consideration after reading Thunt's Twitter feed "1 day, 18 hours until the next Goblins update. I honestly have no idea how you'll react. I may disappear from the internet for a week after":

The whole problem with prophecies is that they are vague. They can be interpreted in many ways. One interpretation might be with the necklace destroyed, Minmax may no longer think of Kin as "normal", just another monster, and may convince Forgath to attack and kill her. But that would imply destroying the necklace also destroyed his memory of the birthday party for Kin, which I don't think has happened. The "serpent" may refer to one of the other Kins, the 'friends to enemies' in Kin turning of the boys or the other Kins turning on them, and the 'love will fuel hatred' may mean Kin starts hunting them or Kin starts hating the other Kins or Minmax coming to hate Kin or the Alt Kins.
But the Seer was telling Forgath his future and the prophecy came AFTER Forgath learned of his fate, so it may have nothing to do with Minmax and the Alt Kins at all. If the "your" in the prophecy is singular, than it is Forgath who will fight the "serpent" and possibly lose Minmax as a friend if that serpent is Kin. Kore might have the ability to influence or charm fellow Dwarves into obeying his order and if Kin changes her mind and goes after them, then she may be Forgath's first target under Kore's control and it is his friendship with Minmax that will be lost. After all, the Seer said 'with' not 'against'. It could also mean that he and Minmax team up with Kore to fight the Goblins (Names' demon sword took the form of a serpent during his fight with Kore). If Kin follows after them, she may try to save the Goblins, as they helped her earlier, which would break Minmax's heart.
Serpent might not refer to Kin at all, but a boss-monster or something, the second and third line may not refer to the boys at all but the Goblins. What ever it is, considering when and where the boys are about to teleport, I fear that we may be losing Forgath and Minmax.
