Remus: Maybe floo to the safe house in Kent first, and from there to the Burrow.

If you do that and bring him to the Burrow, I can break away from work--since it's lunchtime--and come home to speak with him, at least for an hour. It might help, since I was one of the last people to see his Mum. If you think that might help? Or would that be too many wands in the cauldron at this point?
