If she or the others findout about your lycanthropy....I don't know if the effects of silver are the same for a werewolf as it is for a vampire, but if anything other than high-grade silver is used shouldn't be any worse than the other metals.

Yes, his wolf has a name. They're supposedly not able to share the same space at the sametime. That may have to do with his infection being magical and laying dormant for a few weeks.
