Lol imagine that like when some transformer bonds to a human or maybe somehow a human becomes their Conjunx Endura, they can feel each other's emotions and pain alike.
And imagine when the Autobots bonded to their human find out that humans get random pain pangs all over their body but humans are so used to it that they don't notice for a while and if they do notice they just brush it off as nothing.
Optimus enjoying finally some peace and quiet, following Cade around as he has nothing better to do and since his Conjunx doesn't mind then why not.
That is until Optimus starts to feel a very sharp pain in his side, he quickly looks over where Cade is doing his things but.. he doesn't seem really bothered.
After the lain doesn't stop for a while he finally speaks up.
"My star, are you in pain?" Optimus asks, this sharp pang in his side is not lessening.
Cade looks up, processes the question before huffing. "Yeah, but it just happens, don't worry."
Optimus stares at him as Cade starts to do his thing again. 'It just happens?' Optimus can't put in words what he feels right now.
And something tells him that the 'it just happens' is very frequent thing and he doesn't know how to help him.
And that proved to be right after it happening over and over again, whenever the pain is in the head, side, leg, arm. It doesn't matter where, but it always is there.
The same happens to Mirage when he feels very sharp panging pain in his head and side.
It happens to ironhide and Bumblebee alike too.
The Autobots don't know how to help and it's driving them crazy and whenever they ask their humans on why it happens, their answer is always the same:
