As far as I knew there was no convention on name substitutes so, I thought I'd ask you lovely people: what alt-names do you prefer for the characters? (I quite like Sherah Holmes & Dr Joan Watson + Myrtle for Mycroft)
Ooh, I've never seen Sheridan used before but I may adopt that! Weirdly, the only Sheridan I know is Sheridan Smith, who'd actually make a decent Joan Watson...
