Well, spoilers as in what's happened so far in KF2. Namely that there's an adult Kaban and it's implied that Serval got Cerulean'd at some point and lost her memories of her.
Honestly, Tomko looked rattled at the end of the chapter; I thInk her group would sooner be worried about her and a bit cross with Ucchi, though once things settle down, I can totally see this happening.
^^^ But the makeup cliffhanger and this one are magnitudes of importance apart. The makeup cliffhanger was an unresolved gag. The Uchi plot thread is a major one that has lasted many chapters and developed over time. There may be a hopscotch situation in the next chapter, but that's a basic element of plot continuity for the series creators.
^ My concern is that she will regress in her attempts to be kind to others, which has been a delicate one based upon her dependence on the lesson she learned from someone who was profoundly kind to her.
