Sherlock - The moon is a shark

bug-catcher-in-viridian-forest:

THE MOON IS A SHARK
The upper part of the crescent in the Claire de la Lune bottle is separated by water from the lower part. 
The part of the crescent above the water highly resembles a shark fin surfacing from the water (we already know that sharks are one of the main themes of s4).

MARY AS THE SHARK


Claire de la Lune being Mary’s perfume seems to indicate a tie between Mary and the shark theme, possibly with her being the shark herself.

2 FINS = 1 CRESCENT
If the upper part of the crescent is meant to be a shark fin above the water, the lower par of the moon could actually represent the fin reflected in the water.

So the shark might be in fact comprised by two people.
These would reprise the hybrid them from Doctor who’s series 9 (such references are very probable and already frequent, read Predictions based on Doctor Who).

Since the moon is composed by a fin and its reflection, this hybrid might be comprised by two character that mirror each other (either by being similar or by being both similar and opposite).

One example of two characters that would fit this description could be Sherlock and Mary.

As Redbeard too could possibly be an hybrid formed by two people (Red + Beard), the shark could possibly be the same set of characters.
