I am so happy for you Nell getting an interview, I will keep my fingers crossed for you, it is fantastic news.
Pets are funny our dog does things like that, as soon as you leave something unattended for even a second, it's gone.
I personally wouldn't undo your good work on being dark but on the other hand it is a good chance to have some contact so he can see how good you look and how well you are.
This is my thoughts but as I am not "dark" I don't know the consequences of making contact first, so will leave this one to the experts.
I understand though how tempting it would be though.
