Re: → Mingling & Drinking
The Doctor does not know how to flirt, but his friendliness might be construed as such? He'll carry on telling her all about the time he hung out with Madame de Pompadour and the Clockwork Droids and invented the banana daiquiri at a party... then pull a banana out from inside his coat and handed it to her.
Stephen will explain to Charlotte the basics of his magic, should she be interested. He doesn't drink much, and doesn't flirt.
Mycroft drinks moderately and discusses his plans for an antique shop. He's very enamored by her home and the era which she's from (he feels like he'd be very comfortable in the 18th century, but he does his utmost not to show it). He's homosexual, so no flirting for him.
