The Bear - yes, that's the obvious thing but there's no instance of the 1st letter in the grid. I've examined every cell in all 6 directions (and found a few new words in the process - never a bad thing) but discovered nothing relevant. Even the 5-letter English word (being the translation of the obvious one to which you refer) forms a shape with its 5 letters, but does not "read" as a word. More staring, but with dwindling interest. Otherwise a nice puzzle with nice twists, and no, you don't have to skim the novel for the 5 highlighted entries.
