I m not sure what else to state on this matter George And as for the same sex examples people call Bianca and Lena Lianca more than they call them by any other name Lianca short for Lena and Bianca not Bianca and Lena The same goes for Rianca being for Reese and Bianca of course not Bianca and Reese That s why those two articles are titled with Bianca s lovers names coming first And we certainly weren t going to have the articles titled by the portmanteaux But anyway I don t know what else to tell you regarding my feelings about it not making much sense to have this one fictional couple article s heading structurally deviate from all the other heterosexual fictional couple articles I m not about to fight you on this particular instance I just wanted to comment and move on And prominence is key is also original research Like you stated There are no naming guidelines about fictional characters and couples Well except for WP COMMONAME You should see is most sources refer to this couple as Dimitri and Erica or as Erica and Dimitri
