I for one don't see how we can get any real "season closure" in just 2 more episodes... unless the last one involves a sit-down of ALL Soprano family members and a wacked-out Christopher runs in with a bomb strapped to his chest and kills everyone, leaving Carmella, Med and AJ to go on...
And as far as T's sister - don't get me started - Janice has been the "chaos factor" in the show since she came on!
