The three of them are just that old married couple
Shockwave has his strange hobbies, Soundwave is a quiet one and Megatron is the one that does crack
Soundwave is the wife looking out the window waiting for his husband to come back from the war. Doesn’t help that Shockwave presumably offlined and Megatron fucking died. He probably checks and triple checks to make sure he still has them
Both Soundwave and Megatron had thought their Conjunx offlined. To see him again was a welcome sight.
Soundwave had been distressed when Megatron went off into space, leaving him with neither of his Conjunxes and a high chance of loosing both.
Shockwave would be unimpressed but understanding of Megatron’s dark energon escapades. He loves the science behind it but it disapproving of highly unstable self experimentation when Starscream was right there do him a favor for once—
Megatron is quite content with his small Conjunxes. Who wouldn’t appreciate their utter loyalty and willingness to kill someone at the pen drop of a moments notice
Soundwave gets his strength and gun kink time cranked back up to the max. Unrelated, but has anyone seen at how fucking fast Shockwave actually is at running when the camera isn’t focused on him? Bc damn that man can move
Shockwave uses his EM field to blanket his Conjunxes with affection because verbal and physical isn’t really his thing but when he does, helm nuzzles for the win
Soundwave wraps his tendrils around Shockwave’s gun as a form of affection/a hug. He will also do this to Megatron.

Sometimes, Soundwave and Megatron spar for the thrill/fun of it. They are both very familiar with each others style and maybe they also like to show off a little to their Conjunx sometimes. Shockwave just spectates bc he’s at a gross disadvantage with one hand and both his Conjunxes play dirty af no matter who it is
