I make Art?

She pretends she's just a human at first but when they find out they first try to convince her to leave the Decepticons. They want to believe she's still who they befriended and you can't chose who your parents are and she didn't have any other choices of who to join before they came. She's probably just a Decepticon cause it was the only option, right?

Blitzwing would treat her like a kinda ugly pet your friend came home with, doesn't get the allure, but doesn't out right hate her. Though he gets annoyed how something so small can somehow always be in the way or so bothersome. Sari's just like a cat, anytime she senses someone is ignoring her she makes it her mission to be unignorable.

The Decepticons would totally make them at first just to get prime's team out from under their feet and stop being a tripping hazards like cats but turns out OP and some of the others are quick learners to fly in battle.

I think they'd also learn much earlier about omega supreme and the unethical science experiments the autobots have been up to. Bumblebee calls Shockwave/blackarachnia an evil scientist one too many times and they go off on a rant about who the real evil scientists are. Sari's heard it before but she's still paranoid about what Autobot high command will do to her as a techno oragnic. From what Blackarachnia has told her, a quick death would be better.

Also since Sari is the one person they compromise on, I can imagine they occasionally try to see which one of them is her favorite (it's Sparkleplug)

Question of whether or not to register Isaac as Megatron's conjux was not answered in time before Shockwave had to flee.

OH HO HO HO OH! I like how you think.

She stalks them for a long time before actually meeting them. At first she's terrified at the sight of them cause these are the boogeymen of the stories she has been told to her by the Decepticons. As she keeps watching she's intrigued because they don't seem evil, just lots of bickering like her and starscream bicker, they almost seem like a family. Eventually she decides to try to befriend them since this is the first time she's seen other cybertronians that weren't Decepticons. Which while she loves her family, they are all so much older than her, and these autobots must be younger than her cause they haven't gotten their built in weapons that ever warframe gets when they get older. (I like the idea of her thinking everyone is like a warframe who only use external weapons when they are young and get built in weapons as they age. Like wisdom teeth. Thus she thinks the autobots are children like her but like, full cybertronian)

If you'd ask him he'd say that Sari is an excellent warrior, trained by the best (him).

But he absolutely has nightmares and worries every day that the Autobots will invade while he's just a head and defenseless at a disadvantage to protect the things he was learning to love. The relief he had when he was rebuilt and his forces returned before such an invasion happened was immense but not complete. Publicly declaring Earth was protected under the Decepticon Empire while it secured Earth as part of the larger interstellar community. It also brought a lot of attention down on them from Cybertron. Megs does his best to hide Sari from the public so Cybertron doesn't know about her or target her. They know that the Decepticons have a new hacker inhuman (incybertronian?) hacking abilities that keep thwarting the Elite Guards' missions. Megs worries that if they do find out about her, they'll absolutely go after her as the perceived weak point in Decepticon command, either holding her hostage to force him to kneel to autobots or worse putting flight locks on her and forcing her into the mines like how he started.

Sari on the other hand knows the horrors he endured growing up and won't let him ever be a captive of the autobots ever again but doesn't worry too much causes he's Big. Big bot with Big Gun. Who could ever take him down?

Megs def is always on Sari's case about staying safe but she's a teenager who's bad at listening to a nagging parent.
