I skipped season 6, man Marnie was hilarious, she really did shakeup that house. But she was alienated the girls didnt want to hang around with her, so she spent time with the lads instead but the girls still weren't happy with that so ended up making snide comments how she just wants to hang around the lads for attentiom, Holly was the only one to reflect and to actually try include her because she knew how it felt to ostracized and left out.
On season 8, Gaz and Marnie were clearly seeing eachother outside of the house and keeping it on the down low, from the first night theyre kissing and having sex without any build up, then Gary getting jealous and protective over Marnie when Aaron jokingly flirts with her, then Scott getting annoyed because he clearly knows Gary was sleeping with her behind his back and Marnie is lying straight to Scotts face that he is the one she would date and not Gaz, even though Scott is a moron but he isn't an idiot, he knows she's seeing Gaz. Also, they were fighting like a couple, being found cuddled on the couch together when people came back from work like a couple. Also on the night when the lads made the pact to not pull anyone from the house that night, and to only pull a new bird from the club, conveniently Marnie knows about the plan! Cut to Marns and Gaz tashing on and then back at home to have sex and cuddle.
I think the reason why Gaz reacted that way he did with Marnie, and was being everything Charlotte wanted him to be is because Gaz met his match with Marnie, she didn't have the self image issues and the constant desperation of wanting to be loved that Char has. She liked her bit of fun with him but did not give him the reaction he clearly wanted and wouldn't be obsessed with him like Char was/is and had no problem ending it, that clearly bothered him because he knows she doesn't actually care about his feelings, just like how Gary never actually cared about Charlotte's feelings. She even laughs about it with Scott and says "Gary doesn't have feelings you already know that" and Scott agrees with her. He also can't play the "you know i love you to bits" card with her because she isnt like Charlotte she would tell him to duck off and shag his best mate. He truly met his match with her.
Anyways, im thinking of quitting my day job and pursuing an education in History specialising in Geordie shore. But seriously now that i'm much older than when i first watched this show, i see things through different eyes and pick up on stuff much better.
