Carry the Torch, Pass the Knitting Needles

Arthur is the patriarch of the Weasley family, therefore it is his responsibility to keep them together after the loss of one of their own. He struggles, but he will knit this family back together if he has to do it with his teeth. Although... maybe he and Molly can do it together. She was always better at knitting than him anyway.
