In the back half of the Season 1 two-parter in which Todd Mulcahy got hit by a bus, Maggie Lawson played the fiancee who showed up at the hospital, making for an awkward encounter with his crush, Felicity.

“I had this scene where I break down talking to her, and when I went in for the audition, [series creator] J.J. Abrams was like, ‘I’m just going to talk to you for a second,’ and he walked me through the entire story and I started bawling. He then was like, ‘Now do the scene.’ And when we were on set, he was like, ‘Do you want me to walk you through it again?’ I said, ‘Do you mind?’ And he walked me through the whole thing. That’s what a director is supposed to do, but it is rare.”
