You know what could get really weird? If this Daryil remembers Jirra from Jakob's memories.
That's a new layer of weird. What would be weirder is if Ben came to the school instead of Arc. He's even got the clan symbol but he's just a DHS copy of his usual self.
There's also Sierra in Mylenor (but I'm not sure if Daryil's met him). And a lot further away there was another Daryil (http://dhscomix.com/wcomics/wcomic.php?p=75), but he could also have been the same Daryil who knows
i wonder if this is daryil right before getting his third pair.
