I believe many people, like me, were really nervous when they saw Ani going undercover, and they were afraid that she would be found out, but in fact they had prayed for 10 thousand times not to be found out. But Arnie didn't escape the plot that was discovered after all. To be honest, I'm not surprised. After all, many works are often exposed when they are undercover, and they are often exposed because of some small things. This is a great pity.

But to Arnie's surprise, she knew that her identity was exposed, and Arnie would not only stop running but also return to the wall. Why? Personally, I have the following guesses.

First of all, Arnie didn't really realize that he had been exposed. Because in fact, if we read comics, we will find that Arnie was still very swaggering at that time, unlike a person who was arrested. So she didn't realize that she was exposed for a reason.

Another reason is naturally because Arnie knows what she really wants. She wants to reunite with her father, so for this purpose, she can sacrifice everything, even if she is found out, even if she may die because of it, but she still decides to move on and never flinch.

Moreover, I personally think that outside the wall is more dangerous than inside. Outside the wall, Arnie can't find food easily, so he will probably starve to death. Inside the wall, although there are many dangers, at least he can find food. As for other dangers, he can actually solve them slowly later. Besides, there are giants guarding the city walls. Wouldn't it be even worse if it accidentally turned into a giant's food?

Therefore, it is actually a very wise decision for Arnie to return to the Great Wall.
