oh boy, edgy fan art already?
Headcanons: The Titans sometimes end up reading and hearing all the mean things said about them (villains it's fine, but civilians saying these kinds of things is very hurtful because they risk their lives to protect these people). And people throw things at them, insult them, etc. Sometimes the people try to evict or banish the Titans out of fear of their strangeness, etc. Robin is the only one that doesn't get insulted because he's "normal". They try not to let it bother them, but it's hard.
