Particularly in her firing line was Lacey Fuller, who had a one night stand with Jordan before he started dating Megan.
Here's a round up of Megan's most, um, shocking quotes of the episode...
After Jordan says they are the king and queen of Ex on the Beach: "We are making sure no other motherf**kers take our title."
On Lacey: "When I saw that motherf**ker's face, I thought, f**k me, Jordan has been scraping the barrel. She's a four out of ten, mate."
On Jordan: "He gives me a f**king orgasm every night of the week. Let's get that straight, yeah."
On her temper: "I can go like a psychopath if someone pisses me off."
On her relationship: "Me and Jordan are a team. No one will break us. I may go a bit loco but that's only because I love him."
On Lacey's boobs: "They look like f**king lemons stuck on your chest, love. I have real stuff."
On the Lacey / Scotty T / Nancy love triangle: "No offence [Lacey], you're more of a one night stand sort of girl."
On Lewis flirting with her: "Don't mug my boyfriend off babe because I'll mug you off ten times worse."
On stopping rowing with Lacey: "I think she's a piece of s**t on the floor but for me and Jordan's sake and our time in the villa I will zip my lips and just get on with it."
And what the others said about Megan:
Jordan: "When Megan goes she bloody goes. She doesn't listen. When she sees red, she just blurts, not listening to a thing I'm saying."
Lewis: "She's f**king unreal. Ten out of ten."
Jordan: "None of them are f**king good looking apart from Megan."
Olivia: "Megan is one feisty bitch."
Lacey: "I'm going to keep standing up for myself against Megan. F**k I'm in for some serious s**t..."
Gina: "I've never known anything like it. The girl is vicious!"
Jordan: "Any bird I've slept with Megan instantly hates."
Jordan: "I have not seen her mental side in ages so it sort of turned me on a little bit."
