Earlier in the BB3 series, I would have concurred with many in these threads: that Jade sets the hm benchmark in visible backbiting behaviour.
She continues to vacillate between tears & smiles, warmth & distance etc. Yet, in truth, her behaviour hasn't particularly degenerated over the weeks. In fact, it has been eclipsed by that of Adele, Alex, & Tim.
PJ, though, has plumbed a new depth of loutishness. Not content with previously asserting the antiquated male justification of alcohol use excusing sexual behaviour (whilst simultaneously rubbishing his partner's standing), his hypocracy has continued in availing himself of the other services Jade has provided: both domestic & informational.
Perceiving himself to have escaped censor over his actions, his abuse has now escalated - reasons immaterial. The abuse remains directed towards the weakest (certainly educationally & intellectually) housemate - classic thuggish behaviour. It was notable how readily he deferred to Spencer, refusing to challenge an individual more his stature.
For someone who constantly makes reference to a vast array of previous girlfriends, sexual activity, and sheer male prowess - he has demonstrated little appreciation or understanding of how to generate female goodwill - let alone affection. Women are allowed all manner of vote these days; and doubtless will not be moved by the tears PJ shed over a few week's voluntary separation from his family.
If he had been similarly moved by someone else's discomfort, rather than only his own, PJ may have gone some way to redeeming himself. As it stands, he has become the House pig, not Jade.
