RICHARD: Oh, that mouse and I were engaged.
EMILY: Oh, you were not.
RICHARD: I’d given her my pin, I’d introduced her to my parents … The date was set, invitations mailed out.
Although Emily denies that Richard was ever actually engaged to Linny Lott, he claims that a wedding date had been set and invitations mailed out, which sounds pretty solidly engaged to me.
In a former episode, Richard said he almost married a woman named Lucinda Lester, until Emily set her sights on him, due to his prowess at fencing reminding her of her celebrity crush, Errol Flynn.
Although it’s possible that Richard almost married two women with the initials LL he met in college, this does feel like a retcon, with Lucinda becoming Linny. Emily claimed Lucinda had a moustache, something she never says about Linny or Pennilynn.
