Aaron is a shepherd in the Imagination Station adventure Back to Bethlehem. He frequents Benjamin's Inn, and he has a teasing, chiding friendship with Rebekah. When he comes to town, he and his friends go there to eat.
He appears briefly in Back to Bethlehem, Part 2, talking about the fact he's going out into the wilderness to watch his sheep. He enjoys the fact that shepherding is boring and unchanging work, and finds it funny that Connie would have any interest in it. In Back to Bethlehem, Part 3 he comes back to Benjamin (b)'s Inn. He and his fellow shepherds were visited by the angels and as a result they come to the Inn in search of Jesus.
He smells very strongly like sheep from never bathing in the wilderness. Rebekah constantly chides him about it, and nags him to clean himself.
Any family he may have is unknown.
