Alvin stared Morag straight in the face. "We will pass." He declared with a sense of finality. He saw Marwood charge ahead at Morag, the villain raising his mace in preparation. Alvin brought his lance to bear, using his knees to urge Medea to flight. Her midnight wings flapped as they gained altitude, below he saw the Archer knock an arrow and fire at Morag.

"I am no friend of yours, royal, your kind are scum to me, living in your decadence while others suffer for your lifestyle. You're lucky I haven't turned my bow on you yet."

The archer hissed, Alvin barely heard it but the venom in his voice was clear. If that was the case why was he helping us? He DID almost hit Alvin a couple times with stray arrows. Perhaps he should be more wary of this character, and others rallied to help them. Alvin knew Griswal was behind him, as well as his other companions. So he flew over Morag and dove at the fighter that was assaulting Marwood's flank. 
Sure he was bringing a lance against to an axe fight, but he had Marwood there to help him.
