DO YOU SEE HOW NATURAL HE GRABS SHERLOCK’SNECK BUT HOW HE HESITATED ON MARY?!
Isn’t it also interesting that after this announcement, he keeps his eyes on Sherlock and only Sherlock. He snaps out of his shock and breaks out into a huge, bright smile and gives it to Sherlock first. He, without hesitation, grips Sherlock’s neck as if to want to bring him close in celebration: Sherlock! We’re having a baby!
And THEN he turns to Mary and smiles at her. Oh yeah! Mary! And he hesitantly places his hand oN HER SHOULDER. NOT SOMETHING AS INTIMATE AS HER NECK BUT HER SHOULDER.
In the bottom gif, Mary doesn’t even seem to smile until John turns to her. Then she breaks out into this nervous grin. What is she thinking in those seconds when they aren’t looking at one another? She smiles at him and quickly looks away. Why? Shouldn’t she be gazing adoringly into the eyes of her brand new husband and the father of the baby growing inside her?
UNLESS HE ISN’T THE FATHER.
