The apology got to me a little, I think she was being sincere, but it was confusing trying to grasp what it was she was apologising for. She seemed mortified that she'd told someone to leave the house, but there wasn't any indication that she'd recognised it sounded racist.
She did apparently have a "heart to heart" with Shilpa later, but she's claimed to harbour no ill will on several occasions before only to go on to bitch as soon as Shilpa's back was turned.
I agree they're editing it for maximum effect. They often do, and in some places it was really badly done, but as Rich says, they couldn't put words into people's mouths. They cut people's sentences up a few times which might've changed the context a little, but either way, Jade clearly went on a rant. There's no mistaking that.
