The usual goofing around has resulted in an alternate timeline where Molly MacAllister has sextuplets (I'm not sure if it was intended as a joke that even the number of lambs involved sex). Of the six there is but one lone little ram, Ricky.
Further discussion led to the fact that Wolf has volunteered for the occasional "Shearing Day" to give Molly a break once in a while. Apparently there is dissent in the ranks as to whether they should be sheared at all, or at least there is in Ricky's case, since it looks like he's managed to avoid it for a while.
Being of Scottish heritage myself, and their papa Shawn being straight up Scottish, it seems perfectly logical that we'd have shown him how to pleat and wear a great-kilt, and might have helped out with the shield and sword (though it looks like he did most of the work himself from the look of those nails).
