That's how I remember it going down too, ghoulina. The way she asked the question together with the look in her eyes as she said it conveyed (to me at least) that she was denying saying it. At least we were spared the obligatory housewife-pulling-out-phone-to-prove-or-disprove-what-was-said-in-a-text moment.
While it was a totally bitchy moment, I loved Heather's talking head "if you think I'm talking down to you, I probably am...because you are a moron."
And her use of tete-a-tete to say she talked to Vicki. But really, Tamra has to be in on the joke with that stuff right? When Vicki walked in after Heather said that you could hear Tamra faintly in the background in an "oh!" voice saying "you two talked?" - like she didn't understand what Heather had said initially.
