Spoilers, I guess.

I'm at the point where I need to trade the screwdriver with the cups handler to get the old man's bird, but April can't decide on a prize. I've exhausted dialogue with Tobias, Abnaxus, Nebevay, the old man, Westhouse, the map guy, and I've read every book in the Enclave. Is there some trigger I'm missing, or have I screwed up the order? I've reached this point twice, and each time I talked to the cups handler the first time I was in Marcuria.
