Lilith looked around to see the general situation and could see why Ark and his friends were struggling. They were at a disadvantage due to the fact that the area is abundant in light energy due to the being known as Pristina. Lilith could feel the disgusting energy of the Goddess of Light from her.
Gabriel did not charge at Lilith immediately when he gained his balance. He is the composed type and would study his opponent. This is also in favor of his fighting style that becomes more powerful as time passes but he must continue the battle for this to happen. Gabriel's special blessing does not activate continuously as one might think.
