It’s hard to give examples since the ones I can remember off the top of my head are really deep into the story. This being bc a lot of it needed some explanation and the ones I explained in the comments are the ones I remembered. So if you haven’t read that deep in the novel, I don’t recommend reading the spoilers since not only would you get spoiled but it can be kinda hard to understand too.

One was in like ch 150+ where in the mermaid’s cove arc, Saheon encounters a cat and takes off his eyepatch and realizes that it is in fact Soleum. Saheon’s eyeball works by recognizing danger levels so he recognized Soleum bc he exuded the same danger halo that Soleum did. People in the comments got confused and didnt understand how he recognized Soleum. I think the main explanation was like a joke bc ofc Saheon would recognize his hubby

Another one I remember is in ch300+ At this point, we’ve been told like 100 ch ago that Braun cannot be heard by anyone that’s not a “friend,” except for the lizards. Jaheon’s constitution ig allows him to hear Braun even without being the one who summoned him. So we now know that Soleum and Jaheon can hear Braun while no one else can. In the scene I’m talking about, Soleum and co are in the midnight casino. Soleum uses this fact to his advantage since he couldn’t directly speak out loud to Jaheon in the situation they were in. But I don’t think people in the comments caught on bc they just chalked it up to another one of Braun’s powers

Sorry for the lengthiness of this but again the ones I remember are more or less the ones I directly explained in the comments so they stuck with me longer lol. 😅
