Final answer:
There is no information provided that includes a character named Bobby extending an invitation. The scene described relates to a theatre experience, but it doesn't offer enough context to accurately answer the provided question options.
Step-by-step explanation:
The excerpts provided do not explicitly mention a character named Bobby nor do they depict a situation where an invitation is extended to the audience, thus it is difficult to determine what invitation Bobby extends. The provided texts speak about attending movies, a party, and a detailed description of a theatrical experience including various performances and the kinetoscope. Without additional context or information regarding Bobby's role or the setting he is in, selecting an answer from the provided options (A, B, C, D) is not feasible.
However, if we consider the environment depicted, where the audience is waiting for a variety of performances in a theatre, the closest match to 'visit the dark world' in the options could be metaphorically linked to the anticipation and mystique of experiencing a live theatrical performance--often considered an escape from reality, or a 'dark world' in a figurative sense. Nonetheless, this interpretation is purely speculative.
