The two boys have already arrived at their home, while the three who are trailing behind them are only following the remnants of the traces that Darius is following. They are not planning to appear to them, more like they used their pathing to get out of the forest without getting caught up in what the boys said about the shifting movements that the forest does periodically.
It didn't take them too long to get out of the forest, allowing them to sigh in relief. However, they didn't let their guard down. After all, the moment they went out of the forest, not too far from them is a farm. It looks normal from the outside, but for Darius, Io, and Arlo, who are not humans in the first place, they can see what regular humans won't see upon looking at the farm.
