Did Sherlock want to elope with John on the stag night?

miadifferent:

It seems that Sherlock might have relived a more preferable version of the stag night in the Victorian mindpalace waterfall scene.

John slips a bit from his chair and finally touches Sherlock’s knee.

JOHN: I don’t mind.

SHERLOCK: Me too.

[…]

JOHN: Am I a woman? […] Am I pretty?

WATSON: So what’s he like - the other me, in the other place?

HOLMES: Smarter than he looks.

WATSON: Pretty damn smart then.

HOLMES: Pretty damn smart. (*suggestive smile*)

MORIARTY: Ugh - Why don’t you two just elope, for god’s sake!

WATSON: Impertinant.

HOLMES: Offensive.

WATSON: Actually, would you mind?

HOLMES: Not at all.

Then Watson kicks Moriarty down the waterfall. 

He kicks down Moriarty, the allegory of Sherlock’s inner demons that were keeping him from openly falling (in love) with John. John kills of Sherlock’s fears and Sherlock falls, while John is watching and supporting this decision.

He would have eloped with John on the stag night. But he couldn’t fight his Moriarty-demons on his own. He needed John’s help for this.

Nice interpretation.
