Re: A confusing caption
Usually you would expect something else in the past when you use the past perfect. However, in the caption, it could look like he was given the leg right then and there, or shortly before they were talking. Using the past perfect shows that the giving of the leg happened further in the past than the conversation.
Captions are odd in that they often use the present tense, where in simple narrative we would use the past.
Yesterday, he talked to a man who (sometime further in the past) had been given ...
Yesterday he talked to a woman who (just before the conversation) was awarded first prize in the cake decorating contest.
