I've gotten the remark about Myra being MarySue-ish several times now, so I'd like to tell you: I try so hard to make her more human! But somehow it won't come out like I want it to! But please note, that everything is written from Myra's point of view, so if she is constantly picking her nose she won't notice herself because she always does that (as a matter of speaking, of course :P)
And of course, don't see every seemingly good trait as something that makes her more 'perfect'. She's got several 'good' traits that are actually bad traits (is selfish enough to want to be useful even if that means she'll be in the way and thus keeps putting herself into trouble from which she has to be saved, completely ignorant about what other people think and filling it in for herself in not always the best way, keeps asking for compliments by saying 'I'm not that good' = those are no good traits! But they are really common among human-beings ;P)

Imagine you were there

Myra stood a moment panting before she was able to stand up straight and look at the scene before her.

A while ago, Alice had suddenly fallen to her knees and Gilbert's hand had seemed to hurt. Both of them panicked, screaming Oz' name and started running. Myra was wearing the shoes Oscar had made her wear, so she was completely unable to keep up with them.

While following their tracks, she noticed they split up at a certain moment. Following Gilbert's tracks of slipping through the gravel, she finally ended up where she stood now.

Both Oz and Gilbert were sitting on the ground, staring wide-eyed to one of the smaller entrances of the school. Alice was standing next to Oz, shouting at him about being such a useless manservant for disappearing.

"What happened?" She stood firmly.

"H-he just said…" Oz stuttered.

"He said he…" Gilbert stammered.

"Who said what," Myra asked with a sigh, as neither of them finished his sentence.

"Eliot, he…"

"My brother said…"

Myra waited for a moment longer, hoping one of the two would manage more than three words, but she soon noticed it was in vain.

"Really! You men are such children!" She forcefully pulled Oz on his feet. She pulled at Gilbert's arms until he also complied to get up. Gripping both of them at a sleeve, she pulled them into the garden towards the carriage.

"Hey! What are you doing to my manservant!" Alice stamped her foot and followed swiftly.

"Just putting him back into the carriage, so I can search for Mister Oscar without them wandering off again. I'm sick of this! We met Miss Ada, we can go home now!"

She managed to drag the two lifeless men to the carriage, and with the help of the driver she managed to push them both in, ordering Alice in as well. She closed the door and positioned Cheshire in front of it.

"You make sure none of them leaves, okay?"

The black cat mewled and rubbed his head against her leg, before sitting down like a guardian lion.

…

Myra knocked on the door of the principal violently.

"W-who is there?" A male voice asked.

"I am Miss Myra! I've come to collect Mister Oscar Vessalius!"

"Please come in for a moment."

Myra entered the room, seeing a middle-aged man sitting behind a desk, Oscar on a chair on the other side.

"Ah, Miss Myra," Oscar smiled brightly, "I'm so happy you've actually come to get me! I was just taking care of things here, but if everyone is ready talking to Ada, we can leave soon."

"Without intention to be rude, but yes, we are ready. In fact I already put them back in the carriage and we're ready to leave. I'm kind of tired of these games and I've been running around this school on these horrible shoes the entire day. If you don't finish in five minutes, I will."

"And you seemed such a gentle Lady before," Oscar pouted.

"Notice the word 'before'."

"Okay, I'll hurry up," Oscar turned to face the principal again. Myra refused to sit down, standing menacing right behind the jolly uncle until he finished explaining himself to the principal, taking care of the expenses of his presence and apologizing about ten times.

When he finally stood up, Myra bowed slightly to the principal. "Thank you for your time, and also my apologies for what happened." She turned around resolutely and walked out the door, her stance giving Oscar no choice but to follow.

Oscar followed her outside of the building, only to walk beside her when they passed through the garden.
"Is something the matter, Miss Myra?"

"Not really. Just that I find Oz and Gilbert like two dumbfound sheep on the ground, stammering something about some Eliot-guy but not getting any further than the first three words of the sentence. I've been running around all day for nothing. That silly sister of Oz made me remember something painful and if we hadn't come here, we wouldn't have been attacked by those chains either. In summary: it wasn't my best day."

"Chains?"

"A Gate to the Abyss opened. If you want the full explanation, just ask Cheshire or Break. I'm not in the mood to explain."

Oscar took the handle of the carriage-door, but waited to open it, watching Myra closely.

"What did you remember, Miss Myra?"

Myra averted her eyes. "I don't want to talk about it. Not yet."

"Promise me you will talk about it with someone later."

"Why?"

"Don't keep your pains to yourself," Oscar bent forward and forced her to face him, "the longer you keep silent, the more it will hurt."

He straightened his back and opened the door of the carriage. He held out his hand to help her in and smiled gently.

Myra looked him in the eyes for a moment longer, before smiling as well and taking his hand.

"Thank you. I will."

…

"You pretentious beast!"

Myra jumped up in surprise – nearly tipping her tea over – when Miss Sharon barged into the room and hit Oz – who was still chewing on a cushion with a depressed face – unconscious with a paper fan.

"Miss Sharon!" Myra ran up to the place she was trying to hit Oz' brains out and grabbed the arm with the paper fan. Gilbert ran up to them with a startled cry and tried to pick up Oz.

"What's wrong, Miss Sharon," Myra asked while she tried to calm the small woman down.

"H-h-h-h-he…. He!"

"M-Miss Sharon," Myra smiled questioningly.

"Miss Sharon was just upset because Miss Alice revealed she and Oz kissed," Break slowly walked in, a large smirk on his face.

Miss Sharon raised her fan to hit Oz again, but Myra quickly grabbed her arm to pull it down.

"But of course, it was only to sign the contract between them."

Miss Sharon looked up at Break in surprise.

"Illegal contractors just have to get the blood of the chain, then the contract is done."

"I see," Miss Sharon hid her fan behind her back and leaned towards Oz on the ground, smiling cutely. "Really, Master Oz! You should have said that earlier!"

"If I had that chance…" Oz moaned.

Myra helped Gilbert to pick up Oz from the ground and revive him a little, while from the corner of her eyes she saw Oscar enter the room. When they got Oz to look straight from his eyes again, she turned around to see what he had to say.

"…although in the end, we still couldn't figure out who Ada loves… But let's celebrate for everyone's safety! Cheers!"

Oscar came to put a glass in Myra's hand and he smiled brightly at her. She carefully sipped the wine. It was a good wine, she was sure of that.

But when she saw several people drink it like it was grape juice, she already started to dread for the change in atmosphere in the room.

When everyone started to drift off in varying states of drunkenness, she emptied her glass and took her leave. She was too tired for a party of drunks. And she would be taught how to use that gun the entire day tomorrow.

She waved goodnight to Oz, who seemed to be the only one not drunk and took Cheshire with her.

Bah, too lazy to write the drunken-scene. Besides, I might spoil the important moment between Oz and Gil if Myra's in the way.
