He'd just heard of the werewolf attack not long ago, and he was already mentally planning his next big broadcast. The last ones have been rather small and to the point, harrassments of Umbridge in particular and things in general.
He'd automatically worried about Hestia, and somehow this didn't come as a surprise, though he glowered at the thought of that toad going anywhere near Hestia, who really didn't need any more on her plate right now.
Hestia,
Of course I'll take care of the children. My offer always stands, any time day or night, whenever you need it. For however long you need me to. It isn't an imposition at all.
Be careful. Take care with your trip to see the Minister, and if I can help you in any way, please let me know. I'll come around half past eleven so that you'll have plenty of time to get there.
