"Oh," she says and is suddenly struck by the fear that maybe he wouldn't want his mum and dad to know about her at all. She's not posh or a genius. She comes from a lower middle class family. Her job is...not really something to talk about in polite company. She's not very polished in her manner of dress or how she presents herself. She didn't go to public school or to uni at a place like Oxford.

These worries fly through her head as she watches him sit next to her and continue eating like he's not worried. She takes a sip of her coffee and tries to swallow down her fears with it.

"Were you going to tell her? I mean, eventually."

Her voice is quiet but questioning and she pokes at her crepes to do something other than look at him. She can't help but ask. Molly's always been a little bit insecure but Sherlock has always heightened those feelings because he's so...everything.
