For me, Jo defined herself when Shilpa turned to her when Jade was having her tantrum. (Like Sue^ said)

Shilpa: "Jo, are you not going to say anything? I mean, whats going on here?.....

Jo just laughed and didnt really have an answer. Shilpa had put her on the spot to add her opinion on the situation (which Jo was very much a part of), but Jo just didnt have the guts. Showed her true colours.
