If there was any doubt or concern that the twins were magic (there wasn't), I walked into their bedroom to check on them, only to find their crib mobile come to life and flying around the bedroom. Of course I have no idea if I ever pulled stunts like this, but I'm willing to at least bet that Sirius did.
The magic is strong in these two. Ronan, it's safe to say this might be one of their favorite things.
On a sadder note. Vallo can go jump off a cliff. I'll be on my couch with my last bottle of dandelion wine.
