Human reader gets into an accident. RiD01 Skybyte, RiD01 Mirage, and 01 Side-Burn headcanons to them learning that because of the accident, human reader doesn’t remember them.
Of course Sky-Byte's aware of human fragility in comparison to cybertronians, but he didn't realize that some injuries could cause amnesia. And so he's left there, with you staring at him with that look in your eyes—complete unfamiliarity with him who you once called your friend—and now he's just sitting by your bedside because he doesn't know what to do next. But once one of the other predacons suggest hitting you on the head to reverse the amnesia, he snaps at them and hisses that it doesn’t work that way.
Mirage thought that he couldn't be any more disappointed in himself, but upon discovering that you now had amnesia after an accident he failed to save you from, he stood corrected which makes this all the more worse for him. He needs some time alone to mull over this thoughts, but once he comes back he'll take the first step from square one and introduce himself to you all over again.
Side-Burn's seen amnesia and stuff like this before in movies, and so he sorta expects you to become a whole different person and also forget practically everything. He's wrong though, only on the drastic personality change part, not the fact you don't remember things. If you happen to remember other things but can't remember him, this makes it all the more horrible for him to bear. He starts asking T-AI if there's any cure for amnesia, or any way to fix or reverse it, only for her to tell him that this is how it is now and there's no way to fix it.
