Has a very close relationship with her parents Michael and Valerie, and younger foster sister Samantha, (redacted) . Leila is a nature lover, and she and Sean often go rock climbing and hiking together. Leila has a very strong inner core, and is not afraid to meet challenges head on.



Growing up as a science geek, Leila spent all her time with books, and never learned how to swim, which made her feel very self-conscious later in life. This turned out to be a good thing however, as it caused her to meet Sean in college at MIT’s swimming pool their senior year in 2005. She fell for Sean’s nerdiness, and was impressed by his amazing hacking ability; he completely won her over when he maneuvered her name to the top of the online ticketing list for great seats at a Radiohead concert. Sean was a very attentive boyfriend during their time together in college.

Leila’s daily routine was recently thrown into turmoil, (redacted) warning a couple of weeks before Leila and Sean left for their cruise.

Leila is pregnant. ("Arrival")
