Huh, imagine if Pokemon of all anime decided to throw in a lesbian couple! Perhaps that'd convince me to start watching Sun and Moon, if Lillie and Mallow actually became a couple.
Mallow has more "shipping" moments with Ash, and none with anyone else. A youtube video of out of content scenes with Mallow being her friendly self doesn't amount to much.
You really shouldn't try to spread misinformation like this.
