[There's the sense, even for someone like Leon, that he shouldn't be leaving someone completely new on his own in a place like this. Stahn wouldn't be happy about it, and neither would Marian, and they both basically serve as his conscience. But... it really does just make sense to part ways here, he thinks. If Armin is afflicted like that, it's not like Leon would be able or want to keep up.

So he simply nods at the advice, because, well... he'll take it.

And after a long, somewhat begrudging pause, he'll add his own piece of advice.]

What you are looking for is a place to "log out". It will appear somewhere, once all of our tasks have been completed. Stepping through there will take you to the city of Cerealia properly.

[... And that was his good deed for the day, he...tried, now he doesn't have to be sheepish when he sees Stahn next.]
