Shards of Stars au: What if Tfp Starscream, after a lot of time spent realizing and accepting that the Sg cons are exactly what they appear to be (and not about to hurt him), healing from trauma, having some kind of a redemption arc, and dealing with whatever the Sg Autobots had going on. What if the endgame ship was starschock (tfp!ss X sg!sw)?
Tfp Starscream would become a stepfather to like 20 sweet and cuddly test tube babies.
SG Shockwave would actually and exactly have science babies that vary so much, and they all call baseline Screamer "Dad" while they call Shockers "Sire/Creator". Since TFP Starscream "may or may not have been a scientist before the war" (thank you tfwiki for nothing.) I'm gonna learn towards yes, baseline tfp Starscream was a scientist before the war and he's delighted to explore it more again
They'd interact in interesting ways, especially knowing just how much of an empathetic and kind person SG Shockwave is.
