But now you're expanding the set of examples... My point was mostly that his set of examples did not support his claim like he thought they did. What he should have done is not brought up Monroe etc, but the Elric brothers, Death Note, Shea etc and argued that there were many more allusions which were just allusions than there were foreshadowing of future characters and hence an allusion or two to Baba Yaga still left the probability of a future appearance at a risible 1% or something.
