Back at number 14, Mr Darling is asleep in his kennel - his self-imposed punishment for not having kept Nana tied up and thereby losing the children. In fact, he spends all his time in the kennel, being taken in it to and from work - and become a minor celebrity as a result. This particular evening, he asks Mrs Darling to play him to sleep on the nursery piano, which she does so.
 
It is just as this moment that the children return, and indeed the window is open despite Peter's initial plan of preventing the children from returning. The children decide to simply slip into their beds as if they had never been away, and Mrs Darling doesn't quite believe what her eyes are telling her. But finally, we see the tearful reunion.
