When Sherlock walks out the room & says Sorry about dinner. Is he doing more than taunt her? He's sending the message @ the time that he could care less if she dies.
What do you all think? Was there more to that statement than meets the eye?
Also why rescue her after she betrays him by seeking that assistance of his true arch enemy?
Maybe because in finding out he really was her heart, did he find that endearing? Worth risking his life to save her?
Maybe he began craving her morsels?
