I'm sorry for George.
Don't worry too much about Zoe and Copper- you have to give them time to figure each other out. As long as your alpha, it seems like it'll be ok.
And for the nails, when Jemma ripped her nail off the first time, I was as freaked as you were (they bleed so much, my back seat was like a crime scene...)...
It all works out in the end.
