Lancelot beat knight with a stick

Lance puts down his weapons and climbs the tree the hawk landed in. He looks down, and her husband is sitting there with a sword! Lance is like “Dude, are you going to kill me without a weapon?”
And the evil knight, Phelot, goes “Yeah. Screw you, dude.”
Lance shrugs, rips a branch off the tree and beats Sir Phelot to death with it. Then he hands the hawk to the screaming woman and walks away.
