'RHOBH' Tea Time: Erika Girardi Pounces When Teddi Mellencamp Accuses Her of Pretend Amnesia

Welcome to the shark den, baby dolphin!

Teddi went to get her nails done with Lisa Rinna and felt the need to tell her about comments Dorit and PK made three months prior when the Kemsleys had the Arroyaves over for dinner. At the time, Lisa and Dorit had just made amends in Las Vegas, so Teddi found it appalling that Dorit and PK would be talking to Teddi and her husband about old issues -- like the time Rinna accused Dorit of having a coke den in her home. During the dinner, PK suggested that Rinna was schizophrenic, and Dorit said she was stuck in a vicious cycle of rage and regret.

Surprisingly, Rinna was completely unbothered when Teddi told her what Dorit and PK had said.

The next day, all the ladies went out for drinks. On the way there, Teddi rode with Dorit and, in true accountability coach fashion, told Dorit about her conversation with Rinna. Dorit was none too pleased that Teddi felt the need to clear her conscious, even saying, "It's not nice to think you're starting shit with friends of mine. It's not nice to think that you're trying to restart something with someone I've had issues with, which we're working on. For whatever reason, you think your hands are clean. You're not quite realizing that you're starting fires."

The conversation then came up again over drinks, where Teddi was backed into a corner.

"What I'm upset about is that this is a pattern," Teddi said. "If you said nothing that you feel guilty about, then what do you give a f-ck what I have to say?"

That's when Erika chimed in: "She feels like you're starting shit."

"If she feels that way, she should stop saying things that she feels like would probably hurt her friends' feelings," Teddi replied, referencing the New York Fashion Week blowout between Dorit, Lisa Vandeprump and Kyle Richards.

Then Teddi made the dire mistake of saying, "Erika, in the moment, you 100 percent said, 'Teddi, I agree with you, it would've hurt my feelings.'"

"Maybe I did, maybe I didn't -- it's possible," Erika replied.

"You pretending that it's full amnesia right now is confusing to me," Teddi said.

"No, excuse me, don't ever say I'm pretending, because I'm not pretending, I'm telling the truth, I don't remember saying that, don't ever say that to me again," Erika fired back, all in one breath. "Don't f-ck with me like that. You don't want that. Don't. Don't ever, ever do that to me. I'm serious. It's OK. Don't do that."

Teddi ended up in tears, as would anyone with a pulse.

We have a feeling this isn't the end of this battle, as Erika was seen telling someone in the mid-season trailer, "I have one issue: pretend amnesia."
