It takes a few years for the scars to show. Their bruises and petty cuts fade easily, healed over in a matter of days and weeks.
There are some injuries that don't go away, the scarred skin around their wrists from the manacles and a few other scars, tiny in comparison to what they have received from other witches.
They are proud of those scars though. They are reminders of what they have fought, have they have survived, how they keep on surviving, even as everyone else dies. These scars are as much a memento as anything else, only a rather more permanent one.
There is only one mark that they do not like to see, and it isn't even visible.
It is the one constant reminder of their suffering at the witch's hand, and it took at few years to show up - and neither of them are sure why.
They know why it happens though.
That much candy isn't good for anyone, even a child.
