Librarian gives the standard non-answers, which T has already been through and he would continue to get frustrated by explaining he's been over all of that and it doesn't answer it.

And there might even be- you need to figure it out for yourself. Because sometimes you do. but someone else would fly off the handle for that for seeking help doesn't get the answer. It could be incredibly frustrating (even maddening) to have someone seem to be leading you in a direction but only use leading images. "Do you see it? It's by that red sweater in the field of green. Do you see it now? Look harder." Esp to a colorblind person.

So the librarian could easily be giving out what seems like a dead-giveaway clue, and simply repeating words that make utter sense, and for the student to just NOT get it because of other things.
