How Aladdin defeats the Reim army. Sure, he could have obliterated them with his golem's lasers but instead he pushes the entire army all the back to shore and then has the cities shield reestablished forcing the entire army to have to do every step all over again, which Aladdin promises to reverse every time they try. You can see it in the armies faces collectively saying "Not again". How many heroes have defeated an entire army by being a total buzz kill?
Afterwards Kouha and Alibaba fight over Aladdin while a serious discussion continues. Especially funny in the anime where it's drawn out a little more than a one-panel gag.
Chapter 200: Mor is hilariously depressed that Alibaba has a girlfriend. Toto explaining that Alibaba lied about dating her and was just trying to look cool. When the secret is out, Aladdin, Sharrkan and Olba understand, give him a bro hug, and take him drinking and say one day he'll get a girlfriend. Alibaba starts crying in mixed happiness/anguish anyway. All while Morgiana breathes in relief.
There's also the revelation that Alibaba's "girlfriend" was really Garda, the gladiator beast Alibaba fought and freed back when he was in the Reim empire. This page details that there is at least some truth in Alibaba's "lie".
Even the standard message that the manga will be on break for a couple issues gets in a meta joke at Alibaba's expense. "Two week break for Magi in order to heal Alibaba's broken heart."
Chapter 201: Aladdin critiquing Yamuraiha's handiwork when she gives him new clothes and a staff.
Sharrkan getting jealous and angry at Alibaba getting taught by others. Sensing this Olba quickly leaves the room much to Alibaba's dismay.
