Harry and Teddy were in the same crib, lying feet-to-head on either end of the mattress. Harry had somehow Houdini-ed his way out of his own crib and into Teddy’s. Remus and Sirius must not have heard it because of the storm. There was a baby-proofing doorknob cover on the bedroom door, so Harry wouldn’t have been able to get out of the nursery at least, but obviously he hadn’t wanted to. Sirius didn't know what to say. He was shocked.
