hedge supports leo and piper getting together because he thinks they can teach each other things, like how to use a baseball bat and throw balls, so their subpar athleticism combines to create one above-average warrior. hedge is neutral about piper and jason because they don't do anything fun, and they like "talking" and "feeling". hedge is negative about leo and jason because he doesn't like that they're smarter than him together and he doesn't want them to get "ideas" against him. meanwhile, mellie actively prefers liper, not because she believes in them at all, frankly, she doesn't care what the kids are doing, she just wants jason to be miserable.
