Would Emma’s last name and the Swans on Henry’s light be considered LOST references? What about LOST number references? Henry gets off train at gate 4 in pilot; Clock stuck on 8:15, Regina’s house number 108, eye close ups in 8:15 (Emma) and the Heart is a Lonely Hunter (Graham). Someone figured out there were 108 boxes in the EQ’s heart chamber (9×12), Zoso dagger similar to the dagger used in LOST used to try to kill mother, Jacob and man in black; 23 on strangers motorcycle plate; EQ turns into black smoke; Hansel and Gretel wake up on the ground looking up like happened in several LOST episodes; Emma crashed into a sign with the numbers 4 and 23; In Dreamy sister Astrid says they sold only 42 candles.
