*If you look at it logically it makes sense. As for the 'hints' of a romantic Fred and Hermione, in the second book when Malfoy calls her a Mudblood, Yes I realize Ron took a backfired spell for her and definitely received the sympathy vote. However looking at it from the outside. Which is to beat the snot out of him. Considering a person raised in the magical worlds first instinct is in fact magic, it speaks extensively of just how angered he was. Yes, I realize there could be other motive for his reaction but just consider it.
And if all this doesn't make you consider the pairing how about this; Lily and James Potter. Both caring and intelligent witches who stuck to the rules and were thoroughly incensed by pranks played by the marauders/twins. James and Fred were alike in many ways as well, both playing on the Quidditch team, both pranksters, both with a incredible sense of loyalty and both, despite their lack of remorse for their prank victims, had a strong sense of right and wrong."
