Do you think there could have been something between them in real life

I don't think it's exactly likely, but one never knows. I think it is certainly possible Camille might have had dalliances - depends also what weight/interpretation one gives to "un vice privé et honteux" - but I suspect Danton was pretty straight. In all the sources I've mentioned there's quite a lot of slashiness, though. Most of all in the Mantel novel, in which Camille is portrayed as bisexual and rather in love with Danton.

However, just because the sources I picked on this time are all fictional, doesn't mean I have any problem with RPS at all, and I take it from your tone that you do - we'll just have to agree to differ on this one.
