Was I the only one who didn't find last episode's fight scene ridiculous? Two swords or one sword didn't make much difference to me (although I would have liked to see Dawn), and the fighting style was fairly believable. Spinning the swords wasn't just showmanship, it's a defensive move to redirect blows from angles that he can't see. Every time he actually strikes aggressively, it's with a directed blow instead. Don't take my word for it, watch a HEMA (Historical European Martial Arts) instructor review the fight. Certainly not a historically-based fight, but well within the realm of believability.
(^Link being weird, feel free to watch the whole thing).
