"Psylocke and X23. I didn't know either of them were that way inclined, but I think it would be a beautiful thing and whole heartedly encourage them to explore their feelings. Preferably with a videocamera :D"

Jenny Sparks and John Constantine...
Rupert Giles and Zatanna...
Jean Grey and Kyle Rayner...
