I did not read anything other than the title, but I can answer the question without reading the post.

No shenanigans occurred. Shenanigans is a specific term which refers to the situation when first class is inappropriately poached from someone by a GA. Since there is no first class on a regional jet, no shenanigans occurred.

You cannot have shenanigans on a CO regional jet. I suppose on the UA regional jets where there is F, shenanigans could occur. Something for us all to look forward to I suppose.
