Edit: I can talk about what I was drawing here. I've been skimpy on descriptions for a while. Mercury has the problem of being attracted to every pretty filly that gives her the slightest bit of attention. Even in the rare moments she is dating a mare, the inappropriate attractions persist.
She met Gemshine at a friend of her marefriend's birthday party. Cloudy Blossom did not attend. She hit it off with this little filly and ended up holding her hoof. It was a sweet moment despite the suppressed guilt.
