“Um… do you guys remember that one time that she called me, but I thought that it was somebody else?”
“That was funny.”
“Oh, maybe to you. I was mortified.”
“What did you say?”

Just noticed this in A Scandal in Belgravia, during the Christmas party when Sherlock is deducing the present in Molly’s bag for her ‘boyfriend’ and John knows straight away it’s for Sherlock and looks really sad for her.
Not only sad but terrified that Sherlock was about to rip her apart.
John sees more than he’s given credit for.
