Well people i think it is highly unlikely that CBS people are that much dumb that they would reveal some serious info in a promo! The guy that is seen crashing in the window looks more like bertram and not Mcallister!
Also I am still hopeful that we are in for a treat and a huge surprise in the next episode..All those pics that everybody has put up dont prove anything..Also the scar that is put up in the pics is not seen in the promo..So calm down, let your nails grow for the next episode! ;)
