Adoption Nightmare: Brianna is a trickster variant who enjoys being The Gadfly far too much. The more dangerous her targets, the better, such as when she runs away from a furious Skulker while cackling wildly.
Truth and Consequences: This is ultimately the key difference between Adrien and Marinette.
Adrien loves being Chat Noir; even if Hawkmoth were defeated, he doesn't want to give up being a superhero.
Marinette, by contrast, only became Ladybug out of a sense of responsibility, and feels burdened by The Chains of Commanding. Her desire to bring things to an end and have a more peaceful life spurs her to strike a deal with Hawkmoth after learning his Secret Identity, helping him achieve his goals in exchange for his returning the Butterfly and Peacock.
Ultimately, the story ends with Chat Noir leaving Paris to travel the worldfighting evil with Plagg, while Marinette pursues her fashion career in London.
A Teacher's Glory: Hinata finds that she's far more comfortable dealing with hasty meals and long bouts of sentry duty in warzones than she is back home with the haughty Hyuuga and all their luxuries.
Buttercup's disillusionment initially stems from how the girls aren't required to fight crime or monsters anymore, due to various measures put into place to cut down on both issues. Making matters worse is that nobody in her life is helping her find any kind of adequate replacement, aside from Ms. Keane... and that ends when she winds up with a bad case of dead.
After the Time Skip, things only get worse for Buttercup; her scars make the public wary of her to the point that she can't even jump on any of those rare chances for superheroics without being jeered.
, Arya Stark opts to stay and see Roxas fight them off instead of listening to Sansa and fleeing to safety. After being brushed off one too many times, Sansa slaps her sister and calls her a brat for being willing to endanger her life just for some excitement.
