I think it’s often underestimated how much potential for angst established!destiel offers too
twice the worrying about getting ganked
bad guys using the other as leverage/bait
after years of being touch-starved, Cas’ affections get too much for Dean sometimes
Cas taking a while to adjust to having a home
Dean and Cas going infuriatingly slow with their relationship because they’re not sure what exactly the other wants out of this, and they’ve gone too deep with their miscommunication in the past to be able to openly ask
Dean and Cas having their first fight as a couple and, since neither of them have a whole lot experience with long-term relationships, they think the other doesn’t want them back after this
too high expectations for their first time
Cas not staying in Dean’s bed until the next morning and Dean being heartbroken over it every time
Dean sometimes slipping back into his bro-facade around Cas out of habit, making Cas retreat
worrying about their friends not accepting them
hunters/angels looking down on them
Sam being worried that their relationship could cause a shift in the TFW dynamic
Dean and Cas fearing that if they fuck this up, they won’t just lose their partner, but also their best friend
one of them getting cold feet before a next step in their relationship (maybe moving in together?) and leaving for a few days. insert mutual pining
Dean fearing he is taking too long with his first “I love you”
Cas thinking he has to be Dean’s protector now more than ever and Dean being pissed about it
Cas worried that he keeps Dean from having the family with kids he’s always wanted
an ex of Dean turning up, stirring up old feelings. Cas getting it in his head that he has to let Dean go now
Dean getting insecure once his first gray hair appears because soon he’ll be an old man and will Cas still love him then?
