You know, there is a pretty popular theory that Malon and the Hero of Time Link did eventually get together, which would give her even more importance. It is said that TP Link is a blood descendant to OoT Link, so he must have gotten had a kid Through process of elimination we can determine that Malon is the most logical candidate of the OoT harem, as TP Link is not part Zora, part Kokiri, a Gerudo or royalty. We can also conclude that Link is on great terms with her in the child timeline, as he has Epona with him at the start of the game. Add in Talons marriage question, Malon waiting for a knight in shining armor, the fact that TP Link is a ranch hand with a horse that may very well be a descendant of the original Epona(The original Epona was an A tier horse, so they would likely keep the family tree going), and the fact that TP Link knows Epona's song when the original song was noted as being taught to Malon by her Mother(Maybe that tradition continued as well), you get a lot of incidental stuff to go off of.
So needless to say, I would support this character.
