Can You Feel Your Own Back?

Colin is shocked, everyone has always told him how sick and frail he is. No one has ever actually inspected the body and said, nah, you're fine. Colin organises to go outside in his wheelchair, but he orders all the servants to stay away so they won't get busted going into the walled garden. They hang out in secrecy until one day, Ben Weathers stuff, the old garden, other Yorkshire man. So she tells Colin about the secret garden and is to keep it a secret. He grabs Mary's hand and agrees to go out and get some fresh air as long as Mary and Dickin come with him.
