Toaru Majutsu no Index Episode 10

Synopsis
The episode starts during night time; a slender-looking white-haired boy is seen walking out of a convenience store carrying his groceries. Meanwhile, a girl who looks suspiciously like Misaka Mikoto, the Railgun is seen on top of a rooftop, wearing military goggles that a bluish-green color. The girl is holding a mounted sniper rifle, positioned to fire down the streets below. The winds blow her hair, and she speaks in an eerie monotone voice, she adjusts the scope of the gun to accommodate the change in the weather conditions, the target is the white-haired boy. The wind blows again, and once again she adjusts the scope of her rifle, she readies to fire and confirms the target's name, Accelerator. She fires the gun several times, seemingly accurate. The bullet should hit Accelerator, however, in a flash the bullet returns to its bearer, destroying the gun and hitting the girl. She is severely injured, frantically she staggers to run away, apparently afraid of something. She runs into the alleys, and sees the object of her terror. There, awaiting her with a smile, the white-haired boy that should've been killed stands; Accelerator.

Trivia

 * This episode features for the first time the infamous vending machine that eats money, as well as Mikoto's infamous kick.
 * When Maika mentioned that they she and Motoharu during the night maybe a double entrede, considering how Motoharu is sis-con (someone who has sister complex or an attraction to sisters) and that Maika reads manga where siblings develop love for one anoter, which will be referred to later.
 * The episode mentions a school that does not focus on esper development.
 * Though unexplained in the anime, the celtic cross that Aisa has is a magical tool to prevent her powers, Deep Blood, from being detected by vampires.
 * This is the first time Aisa references Touma's incredible luck with girls he meet, which will expand tremendously in later episodes and novels.

Referbacks

 * The monorail bridge seen in episode 1 where Touma is running towards his school is seen again during this episode.

Cultural References

 * The sniper rifle that is used in the beginning of the episode looks similar to a Barrett M82, which seems to have been modified to fire automatically.
 * The flags Aisa is referring to are event flags in many dating simulation games and visual novels, where one can access the story routes as well as other flags of the subject after triggering certain conditions.
 * Tokugawa Ieyasu is referenced by Misaka 10032 during this episode. He was the founder of the Tokugawan shogunate which ruled over Japan for more than 200 years.
 * Erwin Schrödinger is referenced as well by Misaka 10032, as a name for her cat. Here, Touma states that naming a cat Schrödinger is a taboo, which is a reference to his famous thought experiment which included a cat inside a sealed box, that maybe alive and dead at the same time until someone confirms that the cat is either alive or dead when the box is opened. This thought experiment will be used in a later episode, to explain the Power Curriculum Program of Academy City.

Animation Trivia

 * The Misaka clone seen in the opening fires several bullets at Accelerator, however, only 1 seemed to have redirected back to the clone. Also, note there seems to have been little to no recoil at all during the firing of the rifle.
 * Around the 10min 39sec time frame, Misaka puts the night vision goggles on but then has them in her hand in the next scene, and the back on her head in the next.
 * During the scene where Touma argues with Index and Aisa, you can see that Sphinx tail is wiggling back-and-forth, however, if one pays attention, you can also see Misaka 10032's eyes moving back-and-forth as well watching Sphinx's tail wiggling.

Unanswered Questions

 * Is Accelerator the strongest level 5 esper?
 * Why does it seem that there are more than one of Mikoto's sisters?
 * Why is Mikoto's sister fighting Accelerator?
