I'm curious. Why does Kora punch Sebek during Book 2?
Heheheheee! ASK AND YOU SHALL RECEIVE!
So quick reminder, Kora is 16 (Funnily enough, she's like 3 days younger than Sebek... A fact she HATES). But because Kora is 16, she can't always handle everything with grace and poise. She's going to get upset at points and react way more emotionally than intended.
Remember how Lilia basically triggered Leona's Overblot?
Well, in that Overblot fight, Kora got smacked pretty HARD by Leona's Phantom. She got sent flying over half a football field of distance and if not for quick thinking on Riddle's behalf, she likely would've come out of that with a broken neck. Riddle was able to cushion her fall enough that she's just hella bruised and got quite a bit of road rash and scratches.
This is the third overblot Kora has faced and once the fight is over, she's upset and terrified. She's not thinking too clear because she knows she nearly died and she's verging very close to a panic attack. To her, Lilia basically saw Leona on the edge and kicked him off. Kora is shaking all over because she's so freaked out and starts yelling at Lilia because "WHAT THE HELL DID YOU DO THAT FOR?"
Lilia takes her yelling at him quietly and does feel some guilt over it. He knows he knows better than to push a mage who is obviously under duress closer to overblot. He can see Kora is legit terrified given how severe her shaking is and the fact her eyes are overly wide and filled with tears she's trying to hold back. To Lilia, she's basically a very terrified child, so he's letting her letting her yell at him without reacting so she can get out the high emotions as if she were a toddler.
Sebek, however, gets offended on Lilia's behalf. He marches up in front of Lilia, interrupts Kora, gets in her face, and starts yelling at her because "How dare a weakling human disrespect Lord Lilia in such a manner?" He yells at her for a while and she stills, but it's not calming Kora down.
Without warning, she clocks Sebek directly in his left eye HARD. (You're supposed to punch crocs in the eye if they come after you, but Kora doesn't know that, just a fun ref). She does stagger him a little from the shock but, in the process, she cracks a bone in her right hand from the punch. Sebek's hella embarrassed that a human got a hit on him, but in his defense, Kora was not showing any fighting intent until she swung and she swung FAST.
Everybody is stunned. Leona breaks the silence by freaking laughing while Deuce basically has to throw her over her shoulder and run while she's screaming to be put down. Ace and Grim are running behind to make sure there are no pissed Diasomnia students on their tail.
When Ace and Deuce finally do put her down. All Kora can do is just cry. She's tired, she's covered in bruises and scratches, Lilia made things with Leona so much worse, Sebek got all up in her face, and to top it all off, her hand now hurts! Ace and Deuce take a moment to figure out how to handle what just happened because Kora crying super hard isn't something she has done in front of them.
On Sebek's side, he gets a shiner for like a day or two after (half-fae healing at its finest), but he takes it as incentive to work on his training so he can prepare for attacks where there is no hostile intent until the last moment. His main embarrassments are Lilia scolding him for intervening when Lilia was handling it just fine and was letting the magicless child get all her feelings out and the other one? Malleus finds out how he got that black eye and who gave it to him.
Sebek kind of avoids her after though. Crocodile fae half of him is not down to instigate a fight with someone who went after the eyes.
