Witness Protection

Alex was sitting in the waiting room of some lab... he had seen something he wasnt supposed to, some high level member of the [generic organised crime] having some underling killed. He was willing to testify, but due to the high level of danger, he was offered witness protection... a new and experimental form thereof.

so now he was here in some government lab... waiting for what felt like hours before a lab tech approached him.

"alex? we're ready for you now"

alex followed the lab tech as they started to explain things

"so... this surgery will completely reform you into a new body, with a chip implanted in your brain to help you stay on track and not ‘break character’ so to speak (although it might be a bit glitchy)... youll fall asleep on the table and wake up in your new location, beach city... a touristy location... any questions?"

alex finally piped up

"youre not gonna turn me into anything weird are you? And what do you mean by glitchy”

"we cant give any information until youre in your new body... security reasons"

alex is led to a surgical bed... the rest of the room looks more like a mad scientists lab than a surgical theatre.
he lays down on the bed and is put to sleep, counting back from 10... "he" soon wakes up...
