Delilah Kostek

Delilah Kostek is a main character on It's A Mad World.

Personality
Delilah is shown to be very excitable, as she suddenly becomes very vivacious upon learning that Nina's European. She's a big fan of Eurovision, which seems to be something that annoys Ellie. It's also implied that she is hot headed, as Justin needs to calm her down before she even does anything when Ellie snaps at her.
