Wow this is a mess. I do wonder what the national organization itself will do once the suspension is lifted and they (could) return to campus. Considering how popular the house was for a long time, I bet they'll return soon. It sucks that just on the PKT think that has been the thing on SMU's campus for ages lead to this underground organization to exist, as some of these students would rather be in an org that could potentially do harm to them than join one on campus that is seen as "beneath" them.
I rant about this because the exact same thing happened to Tri Delta at Penn State. Hazing incident occurs, chapter gets suspended, and an underground organization called Trilogy forms in its place. Tri Delta had the opportunity to recolonize in 2013, but nationals declined to due to Trilogy being in place (and Penn State was dumb enough to recognize them as a campus organization rather than say don't join this.) Here is more about "Trilogy"
