#Maybe Geoff notices the whole Duncney thing going down and is like “oh pretending to be stupid with love is the perfect disguise”.

What if Geoff wasn't the nice, chill surfer party dude who had no problems with anyone and was friends with everyone?

No, nobody can be that nice. No teenager can be that okay with every person in the camp. No, Geoff hid it. It was a common tactic he used to get people not constantly pissed at him before (it was just annoying). Pretending to be this dumb party dude fooled everyone into believing he was that because why would you ever question HIS motives? He's just a dumb party dude!

But pretending was so, so hard. You see, he had to pretend he liked these people.

Too hard.

And one day, he slipped up.

Interesting. So Geoff's friendly demeanour and sufer boy energy is all, what, a ruse he uses to portray himself as less of a threat in the competition?

It would be an effective game plan; Geoff makes it pretty far into the game in Island, and a lot of his survivability stems from his social strengths and the fact that he's not really seen as a threat in the competition - he's a lot like Owen in that regard, just less intense with his friendliness. You could have Geoff intentionally imitate a lot of Owen's mannerisms after he notices how generally liked (or at least tolerated) he is, and it'd explain their similarities quite nicely.

It does make me wonder what Geoff would be like underneath his act. Your ask implies that he's, if not entirely misanthropic, then a lot less easygoing and amicable as he's shown to be in canon. Someone easily annoyed by others, who perhaps doesn't really have the patience to deal with a lot of the shenannagins that happen on the show, even if he pretends he does... and even if his whole game plan revolves around maintaining that misconception.

That's not to say that he isn't the Geoff we all know and love from canon. He's still the same person, he's just... not as benign. At least not internally.

You could take inspiration for this Geoff from his portrayal in Action, or maybe even his vindicitiveness from World Tour (against Blaineley, just make that energy universal) to base a lot of his real character on; a Geoff who isn't exactly antagonistic, but has a mean streak and a tendancy to hold grudges. And, of course, he'd keep the same natural charisma canon Geoff has, even if his "himbo charm" is fake.

Then it's just a case of replacing his usual good-natured aloofness with cool apathy, or even a spiteful disrgard of others, and you've got yourself the perfect canvas for a wolf in sheep's clothing.

And he's also got his friendships with the Bass boys - Harold excluded, of course - which, considering Duncan's influence, would be a nice outlet for his less sociable tendencies. A way to let loose without having to expose himself as less good-natured than he lets on.

Bringing it back to Owen, and their shared similarities: Geoff could esaily attach himself to Owen post merge, similarly to how Heather attaches herself to Lindsay, as not only a social buffer (though Geoff doesn't really need one, unlike Heather) but as a sort of pawn in the competition. The "boy's alliance" would be the perfect time to have Geoff try to integrate Owen into his social circle, which is pretty much what happens in canon anyway.

Keeping Owen as close as possible is the most strategically sound move on Geoff's part. The closer he is to Owen, the easier it is to cherry pick what aspects of Owen's personality he's going to imitate. He's also got himself at least one secured vote (in theory, since Owen's known to be easily swayed).

The issue with this?

Geoff finds Owen almost unbearable to be around.

Which is ironic, given that he's conciously and intentionally trying to be as Owen-like as possible, but it's true. He can't understand how anyone can be as unconditionally and authentically cordial as Owen is, and it pisses him off. He has a hard enough time acting friendly and warm around people he doesn't like, but when it comes to doing the same with someone he actively despises?

It's enough to wear his already thin patience down until it snaps.
