Answer: Afghan War

The series had previously been set in modern times, so viewers were understandably confused at the start of the episode when it opened at the close of the Second Anglo-Afghan war in 1890s.

The setting ends up being Sherlock imagining what his life would have been back in that timeframe.

Answer: Beating a corpse with a whip

Sherlock was beating the corpse in order to establish how long after death a human body would still bruise.

This was where Sherlock and Dr. Watson were introduced in the 1890s setting.

Sherlock then walked out of the meeting and told Watson to meet him at 221B Baker Street to finalize their living arrangements.

Answer: Christmas

When Insp. Lestrade is first introduced in the episode, he Watson and Mary (Watson's wife) each exchanged pleasantries and a Christmas greeting.

Answer: The foyer was a completely silent room

The Diogenes Club was created by Sir Arthur Conan Doyle and varies depending on plot of the book, movie or TV show it is used in.

Sherlock and the attendant spoke in perfect sign language, while Watson had messed up several words and caused a bit of confusion.

Answer: His mustache disappeared momentarily.

The story, which was mostly set in Sherlock's "Mind Palace". While it wasn't explained in the story, the disappearance of the mustache and his wardrobe changing back to a modern clothes, was simply a glitch in his otherwise thought to be impenetrable fortress of a mind.

There is also a modern reference when Sherlock looks at a picture in a locket that is also a modern photo.

Several times in the story the setting switched 1890s London and modern times.

Answer: Moriarty

He was revealed to be a Math professor in this episode, the first reference to his career as anything other than a criminal.

The entire episode is based around Sherlock trying to figure out how Moriarty could still be alive. The parts in his "Mind Palace" were his way of trying to figure out the resurrection of Moriarty.

In the end he figured out that Moriarty was in fact dead, and his "return" (in the modern world) was only part of a preplanned scheme.

Answer: True

The character is mentioned to be more clever than Sherlock on several occasions.

Answer: Telephone

In the "Mind Palace" version Sherlock's real life was the "dream" as he spoke with Watson about it.

After describing the two items, Watson said he didn't think he'd like it in the future. Sherlock told him that he would and then said that he had always thought of himself as a man out of time anyway.
