Five times Tim Drake gained an unrequited soul bond and the one time he didn't.

So listen, Danny knew going into this PA job that it was a bad idea to work directly under Tim Drake-Wayne. He knows himself, and unfortunately that means he knows his type, which Tim was practically tailor made for. It's like whatever ghost is in charge of the cycle of reincarnation sat down with clockwork to pick out the perfect soul and genetic donors for his future King to fall in love with. He knows for a fact that didn't happen; Clockwork is too much a smug bastard to NOT have poked the two of them into each other's lives yet if that was the case.
