The three Gryffindors and McGonagall stare at him with wide eyes and open mouths. After a moment of silence Professor McGonagall scolded Hermione and took away 10 points for going after the troll and awarded the three boys 5 points each for "sheer dumb luck’ before sending them off to bed. Snape escorted them to make sure they didn’t get into any more trouble; though once they reached the spot where they go different ways he left the three on their own and continued to escort Solis to the Slytherin house. During the walk the Professor had the boy retell what happened and by the time they made it to the dormitory, Solis had been awarded 10 points for his quick thinking and execution for the charm.
