My current theory is that in that stock footage of Lyndsay is some blue screen stuff so that she can inter-react with the in so far as of this date unnamed mother... WHO WILL ALSO BE PLAYED BY LYNDSAY!!!
Problem being is that Lyndsay is a fucking vampire who hasn't visibly aged a fucking day since 2003.
In an interview, she said that they shot all her How I Met Your Mother
scenes because her costar was aging noticeably, but I think she's matured herself. She's not as girly looking.
