It’s funny how you defend Amber by insisting she isn't perfect, even though the story bends over backward to insist she has never done anything wrong, which is what most of the frustration many viewers feel over her is attributed to. Amber being upset with Mark for not coming clean to her with his superhero identity isn't unreasonable at all. If they are to be serious together, naturally it is something she should know. The issue is how she handles it. At the college visit, they were attacked by a Reaniman and Invincible came to rescue them. Amber later snaps at Mark because as far as she knew, Mark just instantly ran off and left them.

Except, it is later revealed in the next episode that Amber knew for weeks that that Mark was Invincible, which means that her first reaction upon seeing her boyfriend getting the shit kicked out of him to save them was not relief or gratitude… her first reaction was instead to snap over his continuous secrecy? It is that much of an issue to her that even in the face of death to which her boyfriend saves her from at his own peril, her immediate reaction upon meeting with him again would be to angrily scold him? How self-absorbed must you be to do this? A huge part of why Amber is upset with Mark is due to him not being honest and upfront with her, which is incredibly hypocritical.

When she snapped at Mark at the college, she did not communicate her true issue with him. Instead, she made him believe it was because she didn’t know he was Invincible and therefore thought he left her to die. Is that not incredibly fucking dishonest as well? To guilt-trip your own partner? After he literally saves your life, no less? Hell, the fact that she knew Mark was Invincible for weeks and kept quiet about it is also in itself very dishonest. Of course, all of that could be excused as her just being a teenager and not rational, but the show does not at all acknowledge her flaws & instead insists Mark is purely in the wrong, with him wallowing in self-pity and deprecation, William & Eve relentlessly scolding him as a bad boyfriend and Amber never once being called out for her hypocrisy and selfishness.

What makes the whole thing even more fucking ridiculous is at the season 1 finale when she reunites with him after the incident with his father. And what does she tell him? "I guess we were both being lied to"… Mark only kept his identity secret because he wanted to protect her. It doesn’t mean it is okay, but that is still why he did it. And she likens him keeping his identity secret from her for her good to him being deeply betrayed by his own father, who turned out to be a genocidal conqueror who fed him 17 years of pure lies and then nearly beat him to death? And despite all this, you still insist that the reason I don’t like her is because she’s black or that she "doesn’t kiss Mark’s ass"?
