Indeed, your assumptions are correct. We can most certainly speak on Saturday. Or, if you need to, even before. I truly mean at any time, even tonight if you need to.
Don't think about what's coming just yet. But, if it will help and she feels comfortable enough with the idea, I can be with her that night so she doesn't have to go through it alone.
Warm Regards, Remus
P.S. I hesitate to say this because I know it's not the sort of thing anyone wants to deal with right now. But, the physical changes occur at different speeds for each of us. It may be prudent to begin noting what silver might be in the house before she is released from St. Mungo's. That's often the first change women notice because of the jewelry they wear.
