How hellish it would be if Bay Megatron finally realizes hes got a sparkling out there? And its Sari?
I got some stuff planned in Bayverse with the Seeker Lennox family, but Megatron wouldn't realize for a very long time...
Optimus, on the other hand, is going through it. Not only his split-spark brother has a bitlet that's very malnourished, but Sari inherited a lot of her missing grandparent's (aka Megatron's and Optimus' carrier) looks, including the colors. And when Sentinel rejoins, the mech will have an epic meltdown. Internally, though. He'll project a calmer demeanor, but he's definitely focused on Sari, who looks like his long-lost Conjunx and the unresolved grief and trauma of losing both his Conjunx and Lord High Protector can fuck up the new generation of the Prime dynasty
Basically is summed up as:
Megatron, suppressing his bonds with long-established practice as he broods over plans to crush his foes and still doesn't realize he got baby running around
Optimus: A child! My brother's child, who is also my child, as we're split-spark twins.... Primus, a child that looks like Carrier
Sentinel: ... You're my second chance at getting this right, and I will ensure that you're properly educated so nothing will go wrong
