The most heartbreaking thing, for me, is when the two people are in love with each other but have not admitted it (and therefore are not a couple, blah blah) and person A is in a relationship with someone else. And then person A is dying, and the other has to watch them die in someone else’s arms.
My reply: OH GOD. YES. DEFINITELY YES. ESPECIALY IN TORCHWOOD. AHHHHHHH.
