These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Jerkass Woobie: Leo. As much of a Jerk Ass as he can be, it's kinda hard not to pity him at times, especially with how Aeris sometimes treats him. Most of his "cruelty" is to fictional characters (such as the Sims example) and things like the baby worm tend to be in the context of strips portraying Leo and Aeris as specific fictional characters being parodied, rather than portraying them in the "usual" characterization.
