Keep in mind they are linked via the Absolute. Big things like "Those jerks just sold us out!" and "OMG, I'm dying!" probably get shared between them.
Then let's see evidence of that! We don't know what "linked via the Absolute" means. This would be a great opportunity for our characters to learn a little bit about what they're up against.
When we get back to the goblin camp, have one of those goblins tell us that they know what we did. Have the narrator mention that they're clearly waiting for us (have them prepared instead of still getting drunk). Have one of our companions comment on the fact that these goblins seem to have figured it out so fast. Hear Minthara send up a call to the Absolute or use sending or something. There are so many ways to make this make sense. The assumption that if you come to blows with one member of a faction means that every other member of that faction instantly knows what's going on (and I imagine this isn't just a thing with the goblins) is lazy storytelling.
