Hi Scarlett, “To protect someone.” After Jude finds Xavier name and makes the call to Cas, and asks him why he left, Cas answers. I thought it was at first Cas trying to protect Jude from Cas but now I am not so sure. Is it to protect Jude from Xavier or from Gideon's games or to prevent Xavier from Jude? I am not sure if you have answered that somewhere else but it is bugging me!
