Elina would put it back. She already had to deal with unwanted voices giving their opinion about what she was doing (especially Ardbert heavily telling her she was making mistakes and sometimes judging her during ShB) so she doesn't want to have to deal with an other one...

Your WoL/OC receives/finds/acquires a talking weapon. Maybe a legendary blade, a confused wand, a pair of knives that argue, or even a book with opinions on what a fact is. Regardless, it talks.
Does your WoL/OC keep it? Trade it in? Put it back? Something else?
