Read in tents, huh? Well, I guess that's ok. Hope it's a good book!
More seriously I'm ok with it in theory, but in our specific case, what could Knife get outta Wic since the two don't share a language? You need to be able to cite how you pick up on the info you gain with RI, right? I guess you could look for non verbal clues outta him, but I'm not sure what those could be used for.
