Okay, so I decided to just publicly yell about Blackspark and the Jettwins. 

Blackspark, currently pregnant enough that it’s visible, runs across the Jettwins and Sentinel on a non-Cybertron planet. Sentinel, as always, is busy being the abusive embodiment of toxic masculinity and Functionalist Autobot ideals, backing the twins into a corner and yelling at them for something trivial. 

Blackspark responds by marching up and punching Sentinel in the face, as hard as he physically can, to which the twins respond instinctively by trying to stop him. Blackspark, rather than fighting them, pulls a trick he’s recently learned and pulses all the carrier-vibes in his field at them as strongly as he can. The twins, who’ve never met a carrier before and didn’t even know Cybertronians could get pregnant, go from impulsive defensiveness to barely-standing compliance, and Blackspark leads them off by their servos. 

Before they get un-dazed, he cuffs them both, just in case, and locks them in the washracks so he can get off the planet without any interference. Gravescratch misses this, opens the door to the washracks to check what’s making noise inside, and is confronted by two hissing, freaked-out Autobot Seekers. 

“Blackspark, what the slagging Pit” 

“rescue mission” 

“…sure, fine, try not to let them shoot you.” 

Once out of chasing range, Blackspark goes and opens the door himself, and the twins, freaked out, start posturing and trying to look brave. Posturing like grounders, too, no flier body language. No wings. Considering he saw them fly down and land, that’s weird. 

Then they tell Blackspark that he’s not going to get them to talk because Sentinel helped them practice for interrogations, and Blackspark’s field roars.

Since they’re busy calling him all sorts of names between the posturing, Blackspark just sits down in front of them, calm, and waits, pulsing care-reassurance-friendliness-carrier-protectiveness, until they get tired, stop swearing, and get confused.

Once they start to calm down, he reaches up with both servos and starts petting their audials, ignoring the half-sparked attempts to bite him. He’s being as unthreatening as he possibly can, and they might not quite know about carrying, but they’ve been to Earth, they know how pregnancy works for humans, and there’s something -someone– else in his field. 

This is thoroughly confusing for the Jettwins, of course. They’re still together, for one thing. They’ve always been told they’d be split up if they were captured, they’ve fought nearly to self-destruction to avoid being captured, and yet they’re still together. And their captor, in addition to not wearing any sort of badge, is petting them. Stroking them, gently, just their audials, field purring, giving them the sort of affection they’ve never had from anyone except each other. 

Before they quite realize themselves, they end up in Blackspark’s lap. Then the cuffs are off, then they start feeling the sparkling stirring against them and the tiny baby greetings reaching out through Blackspark’s field, and that’s it. Adoption complete. They’re thoroughly charmed and 100% convinced that he’s not up to anything. They’ve never had someone treat them like this, and they love it. 

Once he’s figured out that they aren’t about to try and escape, Blackspark reaches up, turns on the shower, and sets about cleaning them up, muttering about how filthy they are. 

Gravescratch probably gets a very thorough inspection as soon as he’ll stand still for them. That’s a good mental image, him sitting with that Look cats get when they’re only tolerating something, rolling his optics towards Blackspark as Jetfire pries his mouth open to look inside and Jetstorm plays with one of his secondary arms. 

Once they’re feeling a bit more confident, Blackspark takes them to someone with a file of new alt modes for them to flip through, gets them an alt mode with actual wings instead of the Autobot-styled grounder shape. Let them use the body language their Seeker subconsciousness is trying to use. They may never quite fit in with born Seekers, but that’s all right, better this than trying to cram themselves into a grounder-shaped slot when their frames want to fly. 

And then they meet Sentinel again. He starts in on them, calling them traitors, deserters- 

And stops when the wings go up. They didn’t have those before. And when did they stop filing their fangs down? Where did they learn to posture like that, like the Decepticons he keeps calling them, like the enemy soldiers he loathes? Where did they learn to stand up to him? 

…when did Safeguard get such a menacing grin? 

That’s how Sentinel gets his aft kicked halfway to the Pit and back and then thrown off a cliff. Y’know, like he deserves. 

That’s also how Blackspark’s kid gets two very enthusiastic uncles/cousins/brothers, and how said kid ends up being lifted, Lion King style, complete with background chanting, shortly after birth. Also with mutterings of “my weird accidental sons are nerds” from Blackspark.
