Ben's Uniqueness
Xander and Ben spoke about many things, and it was during this conversation that he realized he'd actually really wanted someone he could speak to freely.
Even though Ben transmigrated 8 years before him, at the very least, he was able to understand all sorts of earth terms that Xander needed to be careful about subconsciously saying while he was around the others. So it wasn't surprising that the two of them got attached pretty quickly.
There was also the fact that Xander actually understood that Ben was very much neurodivergent. Actually the more they spoke, the more obvious it was.
At first glance, Ben seemed pretty quiet and distracted. Yet when he and Xander started talking, the boy became very talkative, often tripping over his own words and talking very fast, going on tangents until Xander brought him back to the topic at hand, and so on.
