You know don't worry, I didn't even really perceive that as a spoiler! And I throroughly enjoyed the episode anyway, as you said.

Emotionally compromised, oh God your colleagues and students are afraid, aren't they? ;-) I understand what you mean. I am glad I can stay home today and only have to revise for my exam... But the temptation to rewatch the episode ten times is very strong... I will resist! *shakes fist* *breathes* I am strong I am strong I am SHERLOCK!!!!!!
