Hermione/Draco forever? 'Harry Potter' stars discuss fanfics, theories and on-set romances: Watch!

Were Draco Malfoy and Hermione Granger the untold love story of "Harry Potter"?

Tom Felton (Draco Malfoy), Rupert Grint (Ron Weasley), Evanna Lynch (Luna Lovegood), Warwick Davis (Professor Flitwick), James Phelps (Fred Weasley) and Oliver Phelps (George Weasley) joined AOL's In The Know for a game of "Fact or Fanfiction?" — and the answers were quite illuminating, even without the help of Veritaserum. (That's a truth-telling potion, for those a bit rusty on Potter references.)

A full decade after filming the series' final installment in 2009, the co-stars reunited this month at Universal Orlando's Wizarding World of Harry Potter for the opening celebration of the park's highly-anticipated new roller coaster, Hagrid's Magical Creatures Motorbike Adventure.

Felton readily admitted he's stumbled upon a few NSFW Draco/Hermione fan creations: "I feel like I've seen some fanfics along that line," he said. "I've seen some pictures. Some alarming ones."

The cast had mixed feelings on a Draco/Harry pairing, with Lynch and Davis quickly dismissing it but Felton and Grint more open-minded: "Harry was constantly crushing on Draco," Felton insisted. "He just couldn't hide it."

"I think he made quite an impression on Ron, as well," Grint replied.
