Fenrir snarled when the woman kicked out at him and knocked him down the stairs. He was relieved though when Natasha appeared at his side. He spared a moment to lick at her muzzle the followed her up the stairs to the door Lupin's mate was hiding behind. He watched Natasha throw herself at the door and his eyes narrowed when it didn't break under her attack. A quick sniff gave him the answer. Warded.
He nudged Natasha out of his way and started throwing himself at the door. The wood creaked and shuddered under his attacks, the force of the blows making even the walls shake. The door held though and Fenrir stopped and howled his frustration. He scrabbled at the base of the door, trying to hook his claws underneath and pry at the wood that way but the wards kept him from getting a grip. He growled low in his chest and renewed his attack on the door.
