Yes, I think Matilda might need a refresher on Being biology. Not all of that would apply to Dan, but most of it should...
So Matilda has three hearts? That reminds me of a question I saw on Reddit about how many hearts centaurs would have, though I have to admit I always assumed Matilda would have just one, cause one pair of boobs
If Matilda does have three hearts, she'd make a Time Lord jealous by a factor of 0.5.
Liking the detail on Matilda's back. I wonder how longer Amber thought about how taur muscle groups would work?
"His three hearts grew a size that day"?
Nah, I prefer the other version. :D
Yeah I love how Dan is getting to be more and more sure of himself as he grows into a more adult version of himself.
I'm just assuming that she's being a goof. They've both been known to do that (http://missmab.com/Comics/Vol_1087.php), after all.
