You really are incredibly stupid, aren't you?
There has been a series of Rakshata and Lloyd one-upping each other throughout the series, I imagine it will continue.
Up to this point, Lloyd has had the upper hand since the introduction of the Avalon and later the float system for Lancelot. Guren just has that one arm and it seems to get damage/disabled every other time Kallen fights with it. The closest thing Lancelot has EVER had to a loss was the battle at the jailbreak. Right now, though, it's finally the time for the Order of the Black Knight's mecha to be superior for a while.
Not to worry your fanboi head, though, I'm sure Lloyd will have Lancelot outhax Guren again soon enough if it doesn't already (hard to tell since this wasn't a real battle).
