"Plus, Father's still in the bedroom. He hasn't stormed out or kicked John out, like he would if it were Uncle Mycroft he were arguing with."

What a lovely little family cameo!

How worrying that their lovely time in bed had to end with such a revelation; I can see why John's angry (usually his 'anger' is muted, but if he's yelling at Sherlock, he's really angry!), but Sherlock - always logical! - has their immediate future already planned. What happens after that, though, remains to be seen . . . can't wait to find out! (I think! *is nervous*).
