I thought Redbeard was a teddybear with a pirate patch so got that wrong! LOL.
However, it was from childhood and taken away and Sherlock cared too much, but then again how many of us DIDNT guess that! LOL.
When he reverted to the little boy ruffling Redbeards fur, I thought the dog was going to get ripped away from him, maybe like it had when he was little and that nearly brought a tear to my eye. The thought of that little boy, so happy and engrossed in his dog, suddenly being bereft.
