I added 

However, quotes from the crators would be missing and Batman had previous romantic interests prior to this point .

is more sourcing needed? 
I won't change the section any further than that. 

If the creators part isn't aloud I'd need to see Christopher York's sources. We could rephrase "Althoug he didn't quote the creators".

Does anybody saw the "Legends of the Dark knight" ep. of TNBA? there is also a gay reference there.
