Love: it's as easy as 221a, 221b, 221c

When Mrs Hudson finally finds tenants for 221c Baker Street, she asks Sherlock and John to "be nice", but apparently almost blowing up their flat doesn't count. So the pairs quest begins: the quest to befriend the neighbours they almost blew up. But little do they realise the couple of 221c only want the same thing as Mrs Hudson does from the pair, for them to finally admit their feelings.
