The drama shifted to cyberspace on this week's episode of "Mob Wives: Chicago" (Sun., 8 p.m. ET on VH1). After their physical altercation in last week's episode -- that overflowed into the start of this one -- Pia unfriended Christina on the social networking site. But when Christina noticed that Nora had done the same, she started to wonder what that meant."Now I’m thinking -- are they both gonna be in cahoots?” she speculated.Christina wasn't satisfied to let the Internet have the final say, so she decided to meet with Nora in person to find out what was going on.
