Like before leona and Diana were proclaimed canon people were just like oh they were probably best friends.

You got a SUN girlie and a MOON girlie with a childhood friends to enemies dynamic who in the present lore are on opposing sides but also somehow keep finding each other COME ON

We were in the trenches.. sometimes riot would release like side lore in the form of basically fanfics but they weren't accepted for the longest time as canon even though there was SO much subtext. They called us delusional lmao
