Well, he was planning to keep Crowley alive. It is normal that Lucy couldn't pass through the submarine. Since S5, it was shown that even Archangels cannot find, locate someone who has been warded, Angels cannot pass through warded places etc. Pilot holes are nearly 0 I think. Everything is going perfect I think.
