I want to know the answer to the following question:
Which recurring James Bond characters appear in Spectre?
All the background I'm provided with is that "The story sees Bond pitted against the global criminal organisation Spectre, marking the group's first appearance in an Eon Productions film since 1971's Diamonds Are Forever,[N 2] and tying Craig's series of films together with an overarching storyline.". Is that enough to answer the question?
Answer: no
