Greatest Dog here!
Good news and bad news.
Bad news is that Asriel wouldn't crack, even after being given hot chocolate.
The good news is...
Asgore has asked me to dig through and document all of Alphys' old lab reports! All the detailed ones that she had in her computer! I'm officially the "Royal Scribe", now.
Anyway, I'm sharing all of them in a second story on here called "The Lab Files". I'm not great with names. Feel free to read them, though. Alphys will also be taking questions over there. Sans probably will too. Apparently he's in quite a few of those.
