One of the hertasi can help! Illa sleeps in a girls' dorm room on the other end of the floor from where Ma'ar once shared a room with some not-very-welcoming roommates, and the hertasi can take her over there. 

Then Aza will go bother her. Knock knock, Illa.

Illa is a slim dark-haired girl, about fifteen but small for her age. She's sitting by herself on her bed, with a book that she isn't reading; she answers the door and then looks confused and a bit worried. "Uh, hello?" 

"Hi, Illa. I'm Azabel. How are you doing?"

"...Fine?" Illa says uncertainly, staring shyly at the floor. "Do you, uh, want to sit down or something...?" She gestures vaguely at her desk, which has a chair. 

Aza sits. "So the problem with your spell, how bad was it? Did the shield save your life or just your eyebrows?"

Illa flinches, then takes a deep breath. "...I don't know, I wasn't - I guess it looked wrong and I was - being an idiot and should've noticed it wasn't right, but I wasn't done, I'd only put half the power in and then Ma'ar - surprised me, and I triggered it early. It...made a loud scary noise, it singed my notes and they were behind us, but I - I had my eyes closed and it was Ma'ar's shield not mine, I dunno how much force he caught with it." Shrug. "He said it would've killed me, if I'd tried to finish it." 

"Did you visit him in the hospital?"

She shrinks into herself a bit, looking very sheepish. "Nnno. Is - he all right?" 

"No."

Illa turns red and stares at her lap, shamefaced. "I'm - sorry... He was really scary. I'm grateful he rescued me, I thought about - sending flowers or something, but I don't know why he picked a fight with them." 

"He thinks they sabotaged your work."

Illa looks like she's trying very very hard not to cry. "But - that'd be so horrible, why would someone..." She hugs herself. "And why couldn't he have just told the teacher." 

"I wasn't there, I don't know if there would have been time for that before the explosion."

"No, I mean after, we were both fine but then he started yelling at them and then threw a levinbolt for no reason!" 

"Oh, no, yeah, he definitely should have gotten the teacher after. It wasn't no reason, but he still should have gotten the teacher."

Illa nods and shivers. "I'm sorry he got hurt helping me."

"A couple of those boys have track records. Months ago one of them whose name I don't know attacked me in the courtyard while Conn was watching from the shrubbery. I'd have lost my eyebrows, or worse, if I hadn't woken up my mage-gift right then and managed to do shields as my first accidental magic. I'm not sure if Ma'ar's been kicked out of the class and don't have a very strong opinion on it, but I think those boys definitely should be out of it. Will you come with me to talk to your teacher? Since Ma'ar can't right now."

Illa flinches a bit again, then takes another deep breath and lifts her chin, fixing her eyes somewhere around Azabel's left nostril. "...Okay." 

"Do you know where their office is?"

"Adept Liora? Yeah I can show you." 

"Do you wanna stick to the story that you just made the mistake all by yourself?"

Illa's hands twist together. "I...don't know... I was being really careful, I thought, but - I'm not that smart or good at things, Ma'ar said I was but..." 

"I don't think he was lying to make you feel better, it wouldn't really be in character."

"If you say so." Illa seems even more fidgety and embarrassed about this claim. "I just - isn't it more likely I was being stupid than that - people would be that mean for - no reason..."
