Final answer:
The provided dialogue between Harry and Claire does not supply enough information to determine what Henry asks of Mr. Okabe, as no such characters or actions are referenced in the given text.
Step-by-step explanation:
The question seems to be referencing a dialogue from a literary work, but it does not provide sufficient context to accurately determine what Henry asks of Mr. Okabe. However, based on the given dialogue sections between Harry and Claire, there is no mention of Henry, Mr. Okabe, Keiko, or Sheldon. The conversation between Harry and Claire revolves around a key and Harry's desire for salt for his egg. As such, it's impossible to answer what Henry asks of Mr. Okabe based on the provided excerpt. An accurate response would require additional information or context from the literary work in question.
