Changes

In [[9.10 Road Trip]] Castiel removes Sam's tattoo at Dean's request, so that Crowley can possess Sam in order to help him expel [[Gadreel]]. At some point Sam has the tattoo reapplied and it is next seen in [[13.02 The Rising Son]], when he and Dean take Jack to get tattoos. He describes it to the tattooist as "kind of like a family crest."
