A lot of times when you're a fan of a show you wish, pray, and HOPE that two characters will start dating.
For example, maybe you thought Betty Suarez and Daniel Meade from Ugly Betty would be the ultimate ship because you loved how she always cared for him and made him a better person.

Or perhaps you hoped Alex Vause and Stella Carlin on Orange Is the New Black would date because they were both kinda badass and they would be the most ~iconic~ duo.

Or maybe you always wanted Andrea Zuckerman and Steve Sanders from Beverly Hills, 90210 to get together because you felt their friendship always seemed ~deeper~ than what it was.
