I'd say that it all is rather inevitable, although I trust Fred and George (and Hermione and Terry) to keep an eye on them all, and make sure that they don't put anyone in direct danger, and keep what they do know rather tightly buttoned.

I must admit, I'm one part terrified and another part happy to know that Evie has taken up with them. She's so very young, too young, but I've a feeling they take care of their own, so I'm glad she has that.
