Listen, we've all been watching a TV show at some point and noticed the amazing chemistry between two actors.
But has there ever been two characters you thought had the best chemistry, but they DIDN'T even end up together on the show?
Maybe you're like me, and the first people who come to mind are Melissa Benoist and Katie McGrath as Kara and Lena on Supergirl, and as you watch the show, you wonder, "How the heck are these two characters not together yet?"
Perhaps you spent all of The Vampire Diaries obsessed with Candice King and Joseph Morgan's chemistry, but Caroline and Klaus weren't endgame, and you're still sad about it.
Maybe you're baffled by the fact that Jackson and April on Grey's Anatomy didn't get back together before April left, because Jesse Williams and Sarah Drew's chemistry was unmatchable.
Heck, perhaps you were ride-or-die Castiel and Dean from Supernatural because Jensen Ackles and Misha Collins had great chemistry from start to finish, and you can't believe they didn't ride off into the sunset together.
So tell us which TV characters had the best onscreen chemistry but didn't end up together and WHY in the comments below, and you could be featured in a BuzzFeed Community post or video!
