how do those two have phenomenal chemistry with literally everyone else in the cast/world but the second they're in a scene together it's like pbbbbblt.

It's a mystery. God, Bradley looked so bored when they kissed before saying goodbye. I honestly don't know what kind of facial expression he was going for...and I can't stand the music they play each time Arthur and Gwen kiss. They need that to cover up the fact that it's just blah. Merlin and Arthur don't need epic music at all :D
