Well, apparently Riza 2.0 has a name, and...Riza 1.0 seems pretty happy to see him. Everyone else, maybe not so much.
Anyway, normally I wouldn't bother with this and just let you guys theorize, but I'm going to clear up a few things now:
1.) Riza and Faro aren't blood related. The fact that they're so much alike is honestly just freaky coincidence that will likely be joked about at some point. Riza does have a younger brother on Earth, but he's completely irrelevant to the story XD Faro's actually a little older than her.
2.) Faro's not a Dreamer; he was born and raised on Sanvolae.
3.) Riza does have the ability to turn into a full wolf, but that doesn't mean she knows how :P Also, things work a little differently for her as a Dreamer than they would for a "true" half-creature like Faro.
Anyway, now that that's dealt with, Question of the Update: Since you were all pretty much totally off base with this last time, and now that you know they're actually not relatives, I'll basically repeat the last question--just how do you think these two know each other?
PS. If any of you are on Tumblr, I finally got myself a sketch blog (on top of the like, two other Tumblrs I handle...) for all the scribbles and doodles that don't really belong on DA or here or anywhere. Follow away.
