"Yeah, that sounds like a good idea." Alfie hadn't even thought about the possible dangers of having so many magical children all in one place. The accidents that could happen. He wondered, suddenly, if Ellie had thought of all the ways to safeguard herself. He didn't want to see his sister, either of them, hurt because she was trying to do something good.
Then again, Ellie probably had it under control. Right?
"I can help safeguard the place before she gets it open, I guess. Not the charming and such, you're better at that, but I can... I don't know. Pad the walls or something." Which made him imagine a gaggle of wizard toddlers in straight-jackets, and he started to laugh.
